EATON HNC-40/4/003-A 40A 4P 30mA Type A RCCB Differential Circuit Breaker 6kA

The EATON HNC-40/4/003-A is a high-quality residual current circuit breaker (RCCB) designed for reliable protection against earth faults. With a rated current of 40A, 4 poles, and a sensitivity of 30mA Type A, it is ideal for commercial and industrial applications where AC and pulsating DC residual currents are present. This device ensures safety and compliance with international standards.

Advantages

Type A sensitivity detects both sinusoidal AC and pulsating DC residual currents, providing enhanced protection. The compact 4-module design saves space on DIN rail installations. Screw terminals ensure secure and easy wiring. The tripping indicator offers clear visual status, simplifying maintenance.
