Ls Electric 83361634001 Auxiliary Contact Unit 1A1B

Product Description

The LS ELECTRIC 83361634001 is an auxiliary contact unit designed to add supplemental switching capability to compatible contactors and motor starters. Designated as the UA-1 with a 1A1B contact configuration, this unit provides one normally open contact and one normally closed contact for use in control circuits. Electricians and industrial maintenance technicians install this type of add-on block to expand the signal and interlock functions of existing motor control devices without replacing the base unit. It mounts directly to the side or front of a compatible contactor, integrating into the overall assembly cleanly and efficiently.

This auxiliary contact unit is suited for use in motor control centers, panel boards, and industrial control panels where additional contact points are needed for interlocking, signaling, or feedback circuits. Typical applications include conveyor systems, pump controls, HVAC motor starters, and general industrial automation. The 1A1B contact arrangement makes it a versatile choice for both normally open and normally closed control circuit requirements in light commercial and industrial settings.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC guidelines. De-energize and lock out the contactor and all associated control circuits before attaching or removing the auxiliary contact block. Snap the unit onto the designated mounting port of the contactor per the base unit manufacturer documentation before reconnecting wiring. Verify contact continuity with a meter after installation and before returning the system to service.
