Residual current circuit breaker 3P+N 125A 300mA 10kA AC CFC690

Safety and protection in your installation

The 3P+N CFA690 residual current circuit breaker from Hager is a key element ensuring the safety of using the electrical installation. The device is designed to protect people from electric shock and to protect the installation from the effects of short circuits and overloads. This model, with a rated current of 125A and a sensitivity of 300mA, effectively detects leakage currents to earth, disconnecting the circuit in case of a hazard. The breaking capacity of 10kA guarantees a quick response in emergency situations.

Installation and application

The CFA690 circuit breaker is mounted on a DIN rail, which facilitates its installation in electrical distribution boards. Designed for operation in AC networks with a voltage of 415V, it finds application in both home and industrial installations. The width of the device – 4 modules – allows for efficient use of space in the distribution cabinet. The use of a mechanical lock prevents accidental disconnection of the circuit breaker.

Parameters and design features

The design of the circuit breaker is based on 3P+N poles, which provides comprehensive protection of the circuits. Wires with a cross-section from 1 mm² to 50 mm² (solid) or from 1 mm² to 35 mm² (stranded) can be connected using screw terminals. The impact current withstand capacity is 0.25 kA, and the rated impulse voltage is 4 kV. The device operates in a temperature range from -25°C to 40°C and has a protection degree of IP20. Compliance with standards ensures reliable operation and safety of use. Additional possibility of expansion with accessories allows to adapt the functionality of the circuit breaker to individual installation needs.
