Description

Schneider Electric LC1K1210B7 TeSys K Contactor is an electrical device used to control the flow of electrical current in an electrical circuit. It is essentially a high-capacity switch that can be remotely controlled to make or break electrical connections. It is a three-pole contactor, which means it can control three phases of an AC system. AC-3 is the type of load the contactor is designed to handle.

AC-3 is typically associated with the operation of squirrel cage motors. It can handle voltages up to 440V AC and is rated for a maximum current of 12A. It has one normally open (NO) auxiliary contact. This can be used for control signaling or for interlocking with other devices. The coil voltage is 24V AC. This is the voltage required to energize the contactor and close its main contacts.

In summary, Schneider Electric LC1K1210B7 TeSys K Contactor is designed for handling three-phase AC motors up to 440V at a maximum current of 12A. It has an auxiliary contact for additional control options and is activated by a 24V AC coil.
