Product Description
ABB 1SBH137001R1231 NF31E-12 Contactor Relay is a robust industrial control device featuring a 110V AC coil, 4-pole design, and a 6 A contact current rating for reliable switching and motor protection applications.
This contactor relay incorporates a versatile auxiliary contact arrangement with 3 normally open (NO) and 1 normally closed (NC) contacts, enabling complex control schemes and self-locking latching functions to maintain state without continuous coil energization.
The unit is engineered for DIN-rail mounting, allowing rapid, secure installation in industrial control panels where space efficiency is essential. Screw terminal connections provide secure wiring compatible with industrial standards.
Rated to operate efficiently in a wide temperature range from -40°C to 70°C, the relay is suitable for harsh industrial environments. It operates with a control circuit voltage of 130V and supports contact voltage up to 690V AC, making it suitable for three-phase auxiliary circuits and motor protection schemes.
With certifications including IEC 60947-5-1, UL 508, CSA C22.2 N 14, and meeting NEMA and CSA standards, this ABB contactor relay ensures compliance with multiple international safety and performance standards.
The relay’s 3 NO/1 NC auxiliary contacts enable effective make and break control functions. DIN-rail mount offers modular and space-saving panel integration. Screw terminals facilitate industrial-grade wiring security. Broad operational environmental temperature rating supports versatile deployment.
Suitable for motor control, industrial automation, and switching applications. Compact dimensions optimize space in control cabinets. Self-locking latching capability supports holding circuits and motor start/stop control.
Approved by IEC, UL, CSA, and NEMA ensures regulatory compliance.
This ABB NF Series contactor relay is ideal for industrial automation, manufacturing, and motor protection applications requiring reliable electrical switching with modular DIN-rail mounting.
