Circuit breakers shall be draw out type, having SERVICE, TEST & ISOLATED positions with indication for each position. Low voltage switchgear assemblies The main components are: Molded case (MCB) or power (air magnetic) circuit breakers (draw­out or fixed) complete with or without integral overcurrent protection device (thermal­ magnetic, Solid state or microprocessor based) with or without zone interlocking provision Cradle (for drawout versions only) support components to which conductors are connected if such conductors are subJect to any stress when the cover is removed. In this case, a hinged door shall be used instead. Doors and the like provided with hinges shall allow free access and ease of operation of built-in components. 7.1.2.2 Isolating distances Not applicable. Switchgear includes fuses, switches, relays, isolators, circuit breaker, potential and current transformer, indicating device, lightning arresters, etc. that protects electrical hardware from faulty conditions. Let us find out more about switchgear by understanding how it works and what are its different types. What is Switchgear? October 23, 2020. February 24, 2013. by Electrical4U. Generally electrical switchgear rated upto 1KV is termed as low voltage switchgear.
