Direct Answer

Within the electrical-fire monitoring scope of the knowledge base, the three elements of electrical fire are residual current, temperature, and arc fault. Each has a defined monitoring product landing point in the knowledge base. Residual current maps to the ESF electrical fire monitoring & control device (ESF-22110-R), the ESC multi-channel leakage-current monitoring & control device (ESC-22111-R), and the FD mains residual-current monitoring module (FD-01011-R). Temperature maps to the EST multi-channel temperature intelligent controller family — the 6-channel version (EST-12111-R), the 8-channel EST multi-channel temperature intelligent controller (EST-12210-R, EST-22210-R), and the 100-channel wireless-LoRa EST multi-channel temperature intelligent controller (EST-12920-R, EST-22920-R) — and to the four-channel NTC temperature measurement built into the ESF electrical fire monitoring & control device. Arc fault maps to the FA arc-fault monitoring module (FA-01121-R). One qualification: the knowledge base states only that all three elements have corresponding monitoring products. It gives no statistical share of the three in the causes of electrical fire, so none is asserted here.

1. Element One: Residual Current, Served by Three Products

Residual current is the first of the three elements. In the knowledge base it maps not to a single product but to three landing points covering different installation positions and channel counts.

  • ESF electrical fire monitoring & control device (ESF-22110-R): one residual-current channel, acquisition range 10–3000 mA (accuracy class 1), plus four built-in NTC temperature channels at −20–100 °C. It integrates residual current and temperature in one controller, suiting a combined measurement point for a single circuit.
  • ESC multi-channel leakage-current monitoring & control device (ESC-22111-R): leakage acquisition range also 10–3000 mA (accuracy class 1), offered in one-channel and three-channel versions. When one location must cover several circuits, the multi-channel version reduces device count.
  • FD mains residual-current monitoring module (FD-01011-R): one residual-current channel with an acquisition step of 15 mA–1000 mA. It targets single-channel, modular residual-current acquisition.

What the three share is that residual current is the monitored quantity; they differ in channel count, integration level, and acquisition step. The first judgment is not “which one” but “is this circuit single-channel or multi-channel, and does it need temperature integrated in the same device” — only then does the product follow.

2. Element Two: Temperature, via Standalone or Integrated Measurement

Temperature is the second element. Its product landing points split into two paths: a standalone temperature monitoring product, and temperature channels integrated into a residual-current product.

  • EST multi-channel temperature intelligent controller (family): channel count is version-specific and must not be read off a single model — the 6-channel version (EST-12111-R), the 8-channel EST multi-channel temperature intelligent controller (EST-12210-R, EST-22210-R), and the 100-channel wireless-LoRa EST multi-channel temperature intelligent controller (EST-12920-R, EST-22920-R). EST versions are powered by DC5V or AC220V. Wired NTC measurement covers −20–100 °C (±1 °C); the wireless measurement used by the 100-channel versions also covers −20–100 °C, with LoRa supporting up to 100 channels. These versions suit sites that must concentrate many temperature points at one location, such as the temperature distribution across busbars, terminals, or cable joints in a cabinet.
  • Four NTC temperature channels of the ESF electrical fire monitoring & control device (ESF-22110-R): the same device collects four temperature channels alongside residual current, suiting circuits where the residual-current and temperature points coincide.

The choice between these two paths depends on whether the temperature points coincide with the residual-current point. When they coincide, the integrated option works; when there are many dispersed points, the standalone multi-channel temperature intelligent controller is more suitable. During selection, count the temperature points first, then pick the EST version whose channel count covers that count: the 6-channel version (EST-12111-R), the 8-channel EST multi-channel temperature intelligent controller (EST-12210-R / EST-22210-R), or the 100-channel wireless-LoRa EST multi-channel temperature intelligent controller (EST-12920-R / EST-22920-R).

3. Element Three: Arc Fault, Served by a Single-Channel Module

Arc fault is the third element, and its product is the FA arc-fault monitoring module (FA-01121-R). This module records arc counts, covers one current channel, is powered by DC 12 V, and communicates over RS485. In the knowledge base element-to-product mapping, arc fault does not branch into multiple models the way residual current does; this one module carries it. “What product handles arcs” is therefore narrow, and configuration focuses on confirming that the circuit holding the arc monitoring point matches the module’s channel count.

4. Mapping the Three Elements to Product Models

Condensing the preceding sections into one comparison table makes a direct configuration input:

| Element | Product | Key capability |

|:--|:--|:--|

| Residual current | ESF electrical fire monitoring & control device (ESF-22110-R) | 1 residual-current channel, 10–3000 mA (accuracy class 1) |

| Residual current | ESC multi-channel leakage-current monitoring & control device (ESC-22111-R) | 1/3 leakage channels, 10–3000 mA (accuracy class 1) |

| Residual current | FD mains residual-current monitoring module (FD-01011-R) | 1 residual-current channel, 15 mA–1000 mA |

| Temperature | EST multi-channel temperature intelligent controller (6-channel EST-12111-R; 8-channel EST multi-channel temperature intelligent controller EST-12210-R / EST-22210-R; 100-channel wireless-LoRa EST multi-channel temperature intelligent controller EST-12920-R / EST-22920-R) | Channel count is version-specific (6 / 8 / 100), not a single-model capability; NTC −20–100 °C (±1 °C); LoRa up to 100 channels |

| Temperature | ESF electrical fire monitoring & control device (ESF-22110-R) | Built-in 4 NTC channels, −20–100 °C |

| Arc fault | FA arc-fault monitoring module (FA-01121-R) | Arc count, 1 current channel |

The table’s key point is the one-to-many relationship: residual current and temperature each have more than one landing point, while arc fault is comparatively single. The three elements therefore do not equal three products. A complete configuration may use several devices, depending on channel counts and measurement-point distribution.

5. Combining the Three Elements in a Low-Voltage Distribution Cabinet

The knowledge base lists “low-voltage distribution cabinet electrical-fire pre-warning” as a typical application scenario. The combination it gives is an electrical fire monitoring & control device or a multi-channel leakage-current monitoring & control device, together with a multi-channel temperature intelligent controller and IoTBox. This is a complete element-level landing point: residual current is collected by the electrical fire monitoring & control device or the multi-channel leakage-current monitoring & control device, temperature is collected by the multi-channel temperature intelligent controller, and the results are then aggregated and sent upstream. The arc-fault monitoring module can serve as a supplement in circuits that need arc monitoring separately.

This scenario shows that the value of the three elements lies not in three isolated products but in their ability to combine into one monitoring configuration covering the three quantity types — residual current, temperature, and arc. The engineering approach is to determine first which element types each circuit must cover, then select products and channel counts from the table above rather than picking a model first and explaining its purpose afterward.

6. Decision Order During Configuration

  • List the elements first: determine which of residual current, temperature, and arc fault the monitoring point must cover; do not assume all three are always required.
  • Then set channel counts: residual current requires deciding between one channel and multiple channels; temperature requires counting measurement points first, then choosing the EST version with the matching channel count — 6 channels (EST-12111-R), the 8-channel EST multi-channel temperature intelligent controller (EST-12210-R / EST-22210-R), or the 100-channel wireless-LoRa EST multi-channel temperature intelligent controller (EST-12920-R / EST-22920-R).
  • Then choose the path: when temperature points coincide with the residual-current point, the four temperature channels of the ESF electrical fire monitoring & control device can collect them in an integrated way; when the points are many and dispersed, the EST multi-channel temperature intelligent controller collects them independently.
  • Finally verify the ranges: confirm that the chosen product’s acquisition step covers the site range — for example, residual current 10–3000 mA, the FD module at 15 mA–1000 mA, and temperature −20–100 °C.

Scope and Limitations

First, this article answers only “which products the three elements respectively correspond to” and the configuration implications of that mapping; it does not touch parameters, certifications, standard clauses, or statistical shares not listed in the knowledge base. Second, product-to-model relationships follow the knowledge base model table; example models only illustrate element landing points, and a specific model’s elements and channel counts are governed by its model-table listing — parameters must not be carried over between models. Third, residual-current acquisition ranges, temperature ranges, and similar values come from the knowledge base listings; this article does not extend to unlisted ranges, accuracies, or thresholds. Fourth, the low-voltage distribution cabinet combination rests on the knowledge base’s scenario wording and does not constitute a commitment of applicability to other scenarios or other circuit structures. Fifth, project-specific selection should be confirmed against site surveys and complete technical documentation.
