Product Description

The Type A WiFi RCBO 2P 1–40A 30mA Tongou TOWSMR1-40 is an intelligent RCBO (miniature circuit breaker + residual current device) with Tuya/Smart Life connectivity that protects, measures, and automates your single-phase 230 V circuits. It features remote switching on and off, automatic reconnection, event logging, and a comprehensive set of electronic protections: overvoltage, undervoltage, overcurrent, overpower, temperature, and 30 mA earth leakage (Type A, AC and pulsed DC). Thanks to its modular DIN rail design and fast-response electronics, it is the professional solution for homes, offices, and commercial premises seeking safety, control, and efficiency from a mobile device or by voice (Alexa/Google).

Main Features

Intelligent 2P RCBO with integrated 2.4 GHz Wi-Fi communication (IEEE 802.11 b/g/n) on the Tuya/Smart Life platform.
Type A 30 mA residual current protection (AC + pulsed DC) with automatic reconnection function after tripping.
Adjustable thresholds: overvoltage 245–295 V (default 280 V), undervoltage 145–220 V (default 165 V), overcurrent and overpower; typical electronic response ≈3 s.
Thermal-magnetic tripping curve C (other curves B/D available in the series); Icu 6 kA at 230 V.
Integrated class 1.0 measurement: voltage, current, instantaneous power (direct/reverse), energy (direct/reverse), power factor, and frequency.
Frame current adjustment 20–40 A in the TOSMR1-40 version (the TOSMR1-20 variant allows 1–40 A).

Advantages or Benefits

Continuity and safety: disconnects in case of abnormal values and can automatically reset when parameters return to range.
Total control: management via app, scenes, multiple timers, and operation log for auditing.
Energy savings: precise monitoring (class 1.0) to identify peaks and optimize contracted power and usage.
Compact installation: occupies 36 mm (2 modules) and mounts on DIN rail like a standard miniature circuit breaker.
Regulatory compliance: IEC/EN 61009, IEC/EN 50557, EN 301 489, EN 300 328, EMC.

Purpose or Applications

Ideal for single-phase lines for sockets, electric water heaters, light air conditioning, offices, commercial premises, and second homes. In self-consumption systems, it allows automation of loads based on surplus (via Tuya scenes) and remote monitoring of circuit status. For equipment requiring pure DC detection (e.g., certain EV chargers with specific requirements), use a Type B residual current device as specified by the manufacturer.
