    A switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.

They include the following models: 1. Miniature Circuit Breakers (MCB): Miniature Circuit Breakers do not handle currents higher than 100 amps, which makes them suitable for many home and business applications. Once installed, they’re simple to use but not very tunable — you can’t usually adjust their trip settings, for instance. They operate on thermal or thermal-magnetic properties. 2. Molded Case Circuit Breakers (MCCB): These circuit breakers can handle currents up to 2,500 amps, making them a more robust choice for higher-power residential and industrial purposes. With higher amp ratings, their trip load can typically be tuned. What is the difference between MCB and MCCB circuit breakers? MCCBs can handle more voltage, and because of the different requirements set on them, they come in different casing and with different components. Low-voltage circuit b...
