Laser Printing Molded Case Circuit Breaker MCCB

Laser Printing Molded Case Circuit Breaker MCCB is an electrical device used to protect circuits with a shell wrapping and an interior containing key components such as contacts, fuses and electromagnetic releases. When the current exceeds the set value, the fuse will blow quickly, triggering the electromagnetic release to act, causing the contacts to open quickly, thus cutting off the circuit and preventing damage to electrical equipment due to overload or short circuit.
