TONGOU provides high quality residual current circuit breaker(RCCB). Residual current operated protector is a kind of mechanical switching apparatus or combined electrical apparatus which can automatically cut off the circuit when the residual current reaches or exceeds the given value under specified conditions. Also called leakage protector. The rated current of RCCB shall be selected according to the continuous load current it carries.
SCPD (short circuit protective apparatus) must be installed at the upper end of the circuit for protection against short circuits. However, when the RCCB is installed in the same distribution box as the circuit breaker (or fuse) at the lower end (in accordance with the appropriate standard), the SCPD (on the outgoing circuit) can substitute for the short-circuit protection.
Elcb always adheres to the principle of “quality first”, adheres to management informatization, production automation continuously improves production process quality and production management level.
