Electric Moulded Case Circuit Breaker

Electric Moulded Case Circuit Breaker is a kind of electrical equipment with protection functions such as overload, short circuit and under voltage. Its working principle is that under normal operating conditions, the circuit breaker is in a closed state, when the circuit overload, short circuit or under voltage and other faults, the circuit breaker will automatically disconnect the circuit, so as to protect the circuit and the safety of the equipment.

STS3 SERIES 3P/4P MCCB

STS3 SERIES 3P/4P MCCB is a well-known manufacturer of electrical equipment and its molded case circuit breakers have a wide range of applications in the field of electrical protection. Mccbs are manufactured using advanced technology and high-quality materials, and are characterized by high precision, high reliability, and long life.

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.
