Switchgear

Generally Switchgear is a combination of electrical disconnect Switches, Fuses, Circuit Breakers (CB) and it used to control electric power with protection and it can isolate electrical equipment from load.

About Miniature Circuit Breaker or MCB

Miniature Circuit Breaker or MCB has a contact system. That means of arc quenching a mechanism and tripping and protection system to open the circuit breaker under fault conditions during operation like the MCCB. In this post, we will learn about the MCB, MCB’s History, Construction, and Working Principle. What is a Miniature Circuit Breaker? Present days, we use a…

Features of MCCB and ACB with Advantage

You may already see or heard most two common names during your work and that is MCCM and ACB. This two switching device is used to control power in load incoming or outgoing side. But it always depends on the designer which type of switching device is appropriate to control a specific amount of load. These two devices have some…

Low Voltage Switchgear Standards and Testing

Generally, all Switches, Switch Disconnectors, Disconnectors and Fuse combination units are designed to comply with the requirements, Standards, and Testing. All comply with the requirements of IEC 947-3 or EN 60947-3. This also requires a combination of type tests and routine tests before installation. For this reason, normally a sequence of type tests is required to prove that its compliance…

Circuit Breaker Operation Principle

It’s true that switchgear uses to perform the most arduous duty when it is in operation. For better understanding, we will learn about the circuit breakers’ operation in switchgear operating principles. It will be easy to understand the switchgear operation principle if we know the circuit breaker operation principle. So let’s go. Circuit Breaker Operation Principle: Construction: Once I dismounted…

Introduction of Switchgear

Switchgear is responsible to connect and disconnect the electric power supplies and systems. Switchgear is a general term which uses to covers the switching device and its various combinations with some associated control, measuring all parameter, protective and regulating equipment, together with accessories, enclosures and supporting structures. Switchgear mainly applied in electrical circuits and systems from low voltage like domestic…
