HO232-60/HO234-40 Residual Current Circuit Breaker With Over-Current Protection (RCBO)

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

1. it can be wired in either direction.
2.It is accord with IEC 61009-2-1 (mains voltage independent RCBO), It is with electro-mechanical release that works safely even without supply voltage or line voltage lower than 50V.
3.Type -A: Protects against special forms of residual pulsating DC which have not been smoothed.
4.Provides protection against earth fault/leakage current, short-circuit,overload, and function of isolation.
5.Provides complementary protection against direct contact by human body Effectively protects electric equipment against insulating failure.
6.Provides comprehensive protection to household and commercial distribution systems.
7.high breaking capacity up to 10ka.more secure.
