Hager CDS440D RCCB 4P 40A 30mA Type A

The Hager CDS440D is a 4-pole residual current circuit breaker (RCCB) designed for reliable protection against earth faults in electrical installations. With a rated current of 40A and a sensitivity of 30mA, it provides effective protection for people and equipment. The Type A tripping characteristic ensures detection of pulsating DC residual currents, making it suitable for circuits with electronic loads.

• 4-pole design for three-phase systems (230/400V)
• 40A rated current for medium-load circuits
• 30mA sensitivity for personal protection
• Type A for pulsating DC and AC residual currents
• Compact 4-module width for DIN rail mounting

Ideal for use in distribution boards, this RCCB ensures safety and compliance with modern electrical standards. Easy to install with screw terminals.
