China ELCB IEC61009-1 1phase 20a Elcb Rating For Earth-Leakage Circuit-Breaker factory and manufacturers

ELCB IEC61009-1 1phase 20a Elcb Rating For Earth-Leakage Circuit-Breaker

Application

Personnal and fire protection cable and line protection againg stoverload and short-circuits.

General rules for choosing ELCB

■Ratd residual operating current

1Ans30mA: additional protection in the case of direct contact,

1Ans300mA: preventative fire protectionin the case of groud fault currents;

■Tripping class.
