Residual current circuit breaker type A 4-pole FRCmM-25/4/003-A 170332

Safety and reliability in your electrical installation

The Eaton FRCmM-25/4/003-A residual current circuit breaker (RCCB) is a key element ensuring the protection of people and equipment in electrical installations. The device effectively protects against electric shock, as well as against the effects of short circuits and overloads. It is a four-pole type A circuit breaker, which means it reacts to both alternating and pulsating leakage currents – ideal for protecting circuits powering electronic devices, LED lighting or general-purpose sockets.

Functionality and installation for professionals and users

Mounting on a DIN rail (4 module width) is quick and intuitive, which will be appreciated by installers. Terminal block locking provides additional safety when connecting wires with a cross-section from 1.5 to 16 mm² (stranded) or 1.5 to 35 mm² (solid). The circuit breaker is designed to operate at temperatures from -25°C to 40°C, making it suitable for use in various environmental conditions. The IP20 degree of protection provides protection against finger contact, but does not protect against water ingress.

Key features and benefits

• Type A protection: Provides effective protection against electric shock for both AC and pulsating currents – important for modern installations powering electronic devices.
