Residual current circuit breaker type AC 2-pole FRCmM-25/2/003 170391

Residual Current Device (RCD) is a key element protecting the electrical installation from the effects of short circuits and electric shock. The FRCmM-25/2/003 model from Eaton, designed to operate with AC voltage, offers reliable protection in circuits with a rated current of 25A. Mounting is done on a DIN rail, which simplifies and speeds up installation.

Functionality and application

This two-pole AC type RCD is characterized by a sensitivity of 30mA, which provides effective protection for people against electric shock. Therefore, it is used to protect lighting circuits, sockets in residential and auxiliary rooms, as well as electrical devices exposed to moisture. Withstand to impulse current at the level of 0.25kA and high short-circuit strength (10kA) guarantee stable operation even in difficult conditions.

Construction and parameters

The RCD takes up 2 modules on the DIN rail, which allows for optimal use of space in the switchgear cabinet. The housing in RAL 7035 color provides an aesthetic appearance and good integration with other installation elements. The possibility of connecting solid conductors with a cross-section of 1.5-35mm² and stranded conductors 1.5-16mm² provides flexibility in choosing cables adapted to a specific load. The applied lock prevents accidental disconnection of the switch, increasing safety of use. The device operates in a temperature range from -25°C to 55°C, which allows it to be used in various environmental conditions. The rated impulse withstand voltage Uimp is 4kV, which further increases the device's resistance to overvoltages. Protection degree IP20 provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm.
