350A Small Molded Case Circuit Breaker 4 Pole MCCB with Motor Distribution
The UKM30 series molded case circuit breaker is high-tech products in 21st century with advanced design, high performance, pleasant apprearance and delicate dimension.
Description:
Molded Case Circuit Breakers UKM30 series (hereinafter called as UKM30 MCCB) is a new designed MCCB Developed and manufactured adopting international advanced technology. UKM30 MCCB rated insulating Voltage AC 800V is suitable for using in the circuit of AC 50Hz /60Hz, rated voltage up to 690V, rated Working current up to 2500A to distribute electric power and to protect the line and the equipment from being Damaged due to overload, short current and under-voltage. It can also be used for infrequently switch and Starting of motor and for motor overload, short circuit and under-voltage protections. UKM30 MCCB with the Advantages of the small volume, high breaking capacity, short over-arcing (some of specification is zero Arcing), strong anti-vibration and so on.
