The ZMM8 series molded case circuit breakers (hereinafter referred to as “circuit breakers”) are one of the new-type circuit breakers developed by our company using mature design and manufacturing technologies. With a rated insulation voltage of 800V, they are suitable for circuits with an alternating current of 50Hz, a rated operating voltage of 690V and below (400V for ZMM1-63), and a rated operating current up to 800A, used for infrequent conversion and infrequent starting of motors. The circuit breakers have overload, short-circuit, and undervoltage protection functions, which can protect the circuits and power supply equipment from damage.The photo in the 3P MCCB ZMM8-125 MCCB
Introduction to Molded Case Circuit Breakers (MCCBs)
Molded Case Circuit Breakers (MCCBs) are core components in low-voltage power distribution systems, primarily used for overload protection, short-circuit protection, and on-off control of electrical circuits.
The rated current of Molded Case Circuit Breakers (MCCBs) typically ranges from 10A to 1600A, while some high-end industrial-grade models can extend this range up to 2500A.
