Moulded Case Circuit Breaker(MCCB) (RLMC01)

Product Description

Products' brief:
High quality & breaking capacity MCCB
With current adjustable function
Maxi current up to 1600A
For distribute energy of electric and infrequent making and breaking circuit in normal condition
The circuit-breakers are provided with the function of the protection against overload and short circuit and under-voltage
The control circuit of the accessories is set apart with the main circuit, and doesn't need to open the cover of the circuit-breaker when install the accessories
