Schneider Electric LA1SK02 Contactor Auxiliary Contact Block

Product Description

The SCHNEIDER ELECTRIC LA1SK02 is an auxiliary contact block designed as an accessory for contactor assemblies. It adds supplementary switching contacts to a base contactor, allowing control circuits to monitor or interlock with the main contactor's state. This block mounts directly to a compatible contactor and is typically installed by licensed electricians or industrial maintenance technicians during panel builds, motor control center work, or equipment retrofits. The LA1SK02 measures 2.2 inches long, 1.7 inches wide, and 1.4 inches tall, making it a compact addition to space-constrained enclosures.

This auxiliary contact block is rated for use with LC1SK contactors and TeSys SK series contactor assemblies. It is suited for light-duty motor control and switching applications in residential, commercial, and light industrial electrical systems. The block snaps onto or mounts to the side of the base contactor, expanding its contact configuration without requiring a separate relay or additional DIN rail space. Typical applications include HVAC control panels, pump motor starters, and general-purpose motor control circuits.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the NEC and any applicable local electrical codes. De-energize and lock out the panel or control circuit before attaching or removing the auxiliary contact block. Verify that the base contactor model is confirmed compatible before mounting. Do not force the block onto the contactor body, as improper seating can cause intermittent contact operation.
