HB232-40/HB234-25 Residual Current Circuit Breaker (RCCB)

It is electro-mechanical in nature. The highlight here is that:

It can be wired in either direction.

It is accord with IEC/EN 61008-1 (mains voltage independent RCCB), It is with electro-mechanical release that works safely even without supply voltage or line voltage lower than 50V.

Type -A: Protects against special forms of residual pulsating DC which have not been smoothed.

Protection of persons against electric shock by direct contact (30 mA).

Protection of persons against electric shock by indirect contact (300 mA).

Protection of installations against fire risks (300 mA).

Provides comprehensive protection to household and commercial distribution systems.
