Description

Schneider Electric LA1KN11 TeSys K Auxiliary Contact Block is an electrical component commonly used in control circuits for various industrial applications. Auxiliary Contact Block is a module or component used in electrical control panels and equipment. It's used to monitor or control the state of a device or a circuit. 1NO (Normally Open) means that under normal conditions (when no external force or power is applied), this contact is open, meaning no electrical current flows through it.

1NC (Normally Closed) means that under normal conditions, this contact is closed, meaning electrical current can flow through it. Screw Terminal is the type of connection method used in the auxiliary contact block. Screw terminals have a threaded hole into which a wire is inserted and then tightened down using a screw. This provides a secure and reliable electrical connection.

Schneider Electric LA1KN11 TeSys K Auxiliary Contact Block is used in various applications, including motor controls, industrial automation, and electrical distribution systems. They play a crucial role in the safe and reliable operation of electrical equipment.
