Hager CDF640D Residual Current Circuit Breaker 4-Pole 10kA 40A 30mA Type F

The Hager CDF640D is a high-quality residual current circuit breaker (RCCB) designed for reliable protection against earth faults. With 4 poles, a rated current of 40A, and a rated residual current of 30mA, it ensures safety in electrical installations. Type F sensitivity makes it suitable for circuits with frequency converters and other electronic loads.

Advantages

Compact 4-module design saves space on DIN rail. High breaking capacity of 10kA ensures robust performance. Type F RCD provides protection against pulsating DC and mixed-frequency residual currents. Easy installation with screw terminals accepting up to 35mm² rigid or 25mm² flexible conductors.

Suitable for

• Residential and commercial electrical panels
• Circuits with variable frequency drives, inverters, or other electronic equipment
• Protection against electric shock and fire hazards
