Main breaker switch for sale in Turkey

A automatic fuse (MCB) is a type of electrical switch that can cut the electrical current flowing through its contacts when overheating occurs. This prevents damage to the protected circuit. The circuit breaker has three pins connected to each other. One pin is connected to ground. The second pin connects to VCC (Power).

There are three basic types of switchgear: An automatic transfer switch (ATS) is a device that automatically transfers power from one circuit to another when current is interrupted in the first circuit. ATSs, electric motors, heaters, air conditioners etc. It is used to prevent critical loads from being damaged by overload conditions.

A typical household circuit breaker has two settings; normally open and normally closed. When the switch opens, it should stay in this position until the current flow reaches a safe value. If the current exceeds a set limit, the breaker trips and opens the circuit. There are different types of automatic circuit breakers, but they all work the same.

There are two types of residual current circuit breakers in use today: magnetic and thermal. Magnetic residual current circuit breakers (MRCB) are designed to detect any electrical leakage from switched off devices, while thermal residual current circuit breakers detect heat generated by electrical equipment.
