Molded case circuit breakers are robust electrical protection devices designed for industrial and commercial applications. Featuring a durable molded insulation case, they provide reliable overcurrent and short-circuit protection for electrical systems. These breakers combine thermal-magnetic trip mechanisms with adjustable settings, suitable for motor protection, distribution panels, and high-capacity circuits. Common ratings range from 15A to 2500A with interrupting capacities up to 200kA. Key variants include standard, current-limiting, and ground-fault models compliant with UL/ANSI/IEC standards.
