Molded Case Circuit Breakers (MCCBs) are essential electrical protection devices designed to safeguard circuits from overloads, short circuits, and faults. They feature a compact, durable molded case housing and offer adjustable trip settings for precise current protection. Common types include thermal-magnetic, electronic, and motor-protection MCCBs, with current ratings ranging from 15A to 2500A. Key applications include industrial control panels, power distribution systems, and machinery protection. Typical products in this category include: Schneider Electric Masterpact MTZ, Siemens 3WL Air Circuit Breakers, Eaton XT Series, and ABB Tmax XT MCCBs. These devices often include advanced features like remote monitoring, energy metering, and communication capabilities via IoT interfaces.
