Schneider Electric LA1LC010 Auxiliary Contact Block

The auxiliary contact block, also known as auxiliary contact unit or auxiliary contactor, from Schneider Electric is an electrical module for extending switching functions in electrical relays. It has the dimensions 20 x 15 x 10 cm and a weight of 0.31 kg. The OEM part number is LA1LC010. Auxiliary contact blocks extend the functionality of main contactors or circuit breakers by providing additional normally open and normally closed contacts. This enables the implementation of more complex control and signaling circuits. Typical applications are found in automation technology for signaling the switching status of main circuits or in process control technology for controlling auxiliary functions. The spare part is compatible with the 'Bobst Sprintera' machine, among others.
