SCHNEIDER ELECTRIC 21104 - Auxiliary Contact Block
The SCHNEIDER ELECTRIC 21104 is an internal identifier for a modular auxiliary contact block, engineered for seamless integration with the TeSys K series of industrial contactors. This component extends the control capabilities of the primary contactor by providing additional normally open (NO) and normally closed (NC) contacts, crucial for complex control circuit logic, interlocking, and status signaling in diverse automation applications such as motor control centers, HVAC systems, and general machinery control.
