High reputation Circuit Breaker Manufacturer - ZGLEDUN LDM9LZ Series RCCB Residual Current Operated Circuit Breaker, Intelligent Molded Case Circuit Breaker – Elemro

Product Detail:

The product complies with standard GB14048.2-2008 GB/T22387-2008

There is an electronic overcurrent release in the RCCB intelligent residual current operated circuit breaker. The rated current of the circuit breaker is adjustable according to the line load. The three-stage protection curve is adjustable and the RCCB can achieve hierarchical protection with subordinate circuit breakers. The electronic overcurrent release has high protection accuracy and is less affected by the ambient temperature and installation position. It is an upgraded product of the thermal magnetic overcurrent release. There are two types: economical RCCB and standard RCCB.

The smart moled case residual current operated circuit breaker is equipped with an RS485 serial interface which can set the protection characteristic parameters through the programmer. And the RCCB can meet the requirements of communication networking.
