Design Purpose

This NC (normally closed) auxiliary contact block mounts on an IRC5 cabinet contactor to provide an auxiliary feedback contact used for status signaling and safety/interlock logic within the controller. It is supplied as a spare part for contactor sets and maintenance kits, supporting service and refurbishment of existing IRC5 controllers.

Safety & Correct-Fit Notice

Confirm the contact type: 3HAC039834-002 is NC (normally closed). It is not interchangeable with 3HAC039834-001, which is the NO (normally open) counterpart — substituting the wrong contact type changes the interlock/safety logic.
Fit it on the correct contactor in the IRC5 cabinet (AF26 3HAC039832-001 / AF9 3HAC039833-001 families); confirm the contactor type before installation.
Always de-energize and apply lockout/tagout (LOTO) to the IRC5 controller before handling contactor assemblies — their contacts carry hazardous voltage.
Confirm whether you need new or used original; condition must be agreed before ordering.
Verify the exact part against your controller's spare-part list and nameplate.

Common Failure Modes

Contact bounce or poor contact from repeated switching
Contact welding or pitting under load
Spring fatigue preventing proper open/close action
Oxidation or contamination on contact surfaces
Mechanical clip wear causing loose mounting on the contactor
