Residual current circuit breaker 3P+N 25A 30mA 10kA F CDF625D

Safety and reliability in your electrical installation

The 3P+N CDF625D residual current circuit breaker from Hager is a key element ensuring the protection of people and equipment against electric shock and the effects of short circuits. The device is designed for use in electrical circuits with a voltage of 400V and a rated current of 25A, offering effective protection with leakage currents of 30mA. Thanks to its high short-circuit breaking capacity of 10kA, the circuit breaker provides a quick response in emergency situations, minimizing the risk of damage.

Construction and installation

The circuit breaker is designed for mounting on a DIN rail, which facilitates its installation and integration with existing electrical systems. Compact dimensions (70 mm mounting depth and 4 modules width) allow for efficient use of space in the distribution board. Screw terminals allow connection of wires with a cross-section from 1 to 25 mm² (solid) or from 1 to 16 mm² (stranded), ensuring a solid and durable connection. An additional mechanical lock prevents accidental opening of the device during operation.

Application and benefits

This type F residual current circuit breaker is particularly recommended for use in installations with devices generating interference, such as inverters or impulse power supplies. Its characteristics allow for correct operation even in the presence of pulsating DC currents, which increases the safety and reliability of the system. The rated impulse withstand voltage of 4kV guarantees resistance to overvoltages, and the high operating frequency (50 Hz) ensures compatibility with most electrical installations. The circuit breaker meets safety standards, confirming its high quality and reliability. Suitable for operation in a wide temperature range (-25°C to +70°C) makes it suitable for various environmental conditions.
