The AC contactor auxiliary contact block is an essential accessory designed to enhance the functionality of AC contactors by providing additional auxiliary contacts for control and signaling purposes. Typically mounted directly onto the main contactor, it features normally open (NO) and/or normally closed (NC) contacts that operate synchronously with the contactor’s coil. These auxiliary contacts are widely used in electrical control circuits for interlocking, status indication, or sequential operations in industrial and commercial applications. Constructed for durability and reliable performance, they are compatible with standard contactor models, ensuring easy installation and maintenance.
