Schneider Electric LUA 1C20 Auxiliary Contact Block

The auxiliary contact block, also known as an auxiliary contact, additional contact, or signaling contact, from Schneider Electric with type number LUA 1C20 is an electrical contact switch that functions as an integral component of contactors to implement additional switching functions in control circuits. It has the dimensions 7 x 2 x 2 cm and weighs 0.7 kg. Auxiliary contact blocks extend the functionality of main contactors by providing feedback on the switching status or enabling interlocks in complex control systems. They are typically used in machine control systems, automation systems, and industrial plants to monitor switching states and implement logical operations.
