Schneider Electric LA1SK20 Contactor Auxiliary Contact Block

Product Description

The SCHNEIDER ELECTRIC LA1SK20 is an auxiliary contact block designed as an accessory for contactor assemblies. It mounts directly to a compatible contactor to add or expand auxiliary switching contacts, allowing control circuit monitoring, interlocking, or signaling functions alongside the main power switching. This type of accessory is standard in commercial and industrial electrical panels, motor control centers, and HVAC equipment control circuits. Licensed electricians and industrial controls technicians typically install this component during panel builds, equipment commissioning, or field service repairs requiring expanded contact capacity.

The LA1SK20 is rated for use with LC1SK series contactors. It is commonly found in light commercial and industrial applications where compact contactor accessories are needed to support control logic, status indication, or safety interlock circuits. The block snaps onto the contactor body without additional hardware, making it a straightforward addition during initial installation or retrofit work.
