DPX Type Molded Case Circuit Breaker
DPX Series molded case circuit breaker
is one of the most advanced type breakers in the world, which adopts international advanced design and manufacture technology. They are suitable for short circuit and overload protection for the circuit of AC 690V 50/60Hz, rated current from 12.5A to 630A. Its rated insulation voltage is 690V. It can make and break the non-frequently circuit in the normal conditions. It takes protect effect when mouse cage motors non-frequent start, breaking off working and protecting overload, short circuit and lacking voltage. It complies with IEC60947-2.
Function and Features
1. Select material is excellent the flame-retardant material. Insulation performance is high-temperature residents. 2.Copper pieces of thick. Adopt and thick galvanized sheet copper. Not easy to slide wire electrical conductivity. 3.The new more accord with the aesthetic. Nover appearance Color coordination. 4.Wire facing Not easy to slide wire. Uses the socket head screws.
