Molded case switches, commonly referred to as MCCBs (Molded Case Circuit Breakers), are indispensable components in modern electrical systems. These devices play a crucial role in ensuring the safety and proper functioning of various applications by protecting circuits from overloads and short circuits. With their robust design, advanced features, and widespread applicability, molded case switches have become an essential tool in electrical engineering and power management.
Design and Features
Molded case switches are designed to handle higher currents compared to residential circuit breakers. They consist of a durable molded case housing that encloses the switching mechanism. The internal components are designed to withstand high temperatures and electrical stresses, making them suitable for a wide range of industrial and commercial applications. These switches offer various features that enhance their functionality: Overload Protection:One of the primary functions of molded case switches is to protect circuits from overloads, which occur when the current exceeds the rated capacity of the circuit. The switch’s thermal-magnetic trip unit detects these overloads and interrupts the current flow, preventing potential damage.
