The most popular product among AISO products–MCCB

Molded case circuit breakers are also called device-type circuit breakers. All parts are sealed in a plastic case. The auxiliary contacts, undervoltage releases and shunt releases are mostly modularized. Due to its very compact structure, molded case circuit breakers cannot be overhauled. It mostly adopts manual operation, and large capacity can choose electric opening and closing. Due to the application of electronic overcurrent releases, molded case circuit breakers can also be divided into two types: A and B. Type B has good three-stage protection characteristics. However, due to price factors, thermal magnetic releases are used. A-type products have a higher market share. Molded case circuit breakers are equipped with contacts, arc extinguishing chamber, trip unit and operating mechanism in a plastic shell. Generally, maintenance is not considered. It is suitable for branch circuit protection switches. Overcurrent releases have thermomagnetic There are two types of thermal-magnetic molded case circuit breakers. Generally, the thermal-magnetic molded case circuit breaker is a non-selective circuit breaker. There are only two protection methods: overload long delay and short circuit instantaneous protection. Electronic molded case circuit breakers have overload long delay and short short circuit protection. Four protection functions: time delay, instantaneous short circuit and ground fault. Some of the newly launched products of electronic molded case circuit breakers also have a regional selective interlocking function. Most molded case circuit breakers are manually operated, and some have motor operating mechanisms

AISO’s MCCB is made in strict accordance with industry standards, and the quality is very good. It sells well in Central Asia, Europe and other countries, so it is trustworthy
