Applications
Auxiliary contactor relays like the ABB N31E are used throughout industrial control panels to switch low-power control circuits — typically for signaling, interlocking, sequencing, and logic functions in motor control centers, machine tool panels, and process automation systems. The N31E belongs to ABB's N-series auxiliary relay family, which is designed to work either as standalone DIN rail-mounted control relays or as add-on auxiliary contact blocks alongside ABB's A-series contactors. With its mixed 3NO+1NC contact arrangement and broad AC coil input range, this relay suits applications where multiple control functions must be switched simultaneously from a single coil command. Its IEC and UL dual certifications make it suitable for both European and North American industrial installations. This series dates from the era of ABB's classic N-series product line and remains in use in legacy panel retrofits and OEM machinery maintenance worldwide.
This ABB N31E auxiliary contactor relay has been inspected and appears to be in good used condition. It was pulled from a working environment where it was previously in service. The unit shows normal light wear consistent with use — contacts and terminals look clean, the housing is intact, and the DIN rail clip is present. Please review all photos and contact us with any questions before purchasing.
