Today we will learn about magnetic contract. Magnetic contact is an electromagnetic mechanical switch. This magnetic contract is maximum (12,500AMP).

This magnetic contract is used to control large motors in large industrial plants. Sometimes relays can also be used. But the relay is used in low voltage. And magnetic contracts are used at high voltage. This magnetic contact is mainly used in three-phase motors.

This magnetic contract has an internal coil. The magnetic contract coil has two terminals (A1, A2). For three-phase connection, upper site has L1, L2, L3 and lower site has T1,T2,T3 connection terminals. Also this magnetic contract coil has NO, NC auxiliaries.

Contact Auxiliary NO,NC

This magnetic contract coil can be used on both AC and DC lines. These coils can generally be of different ranges like:- AC- 110V, 220V, 360V, 440V and DC- 24V can be operated. We use these magnetic contracts to protect our large batteries.
