1SBH137001R1331

ABB NF31E-13 (1SBH137001R1331) is a 4-pole contactor relay with 3 Normally Open and 1 Normally Closed auxiliary contacts, designed for switching auxiliary and control circuits in industrial electrical systems.

It uses ABB’s electronic wide-range coil interface, allowing one device to operate from 100–250V AC 50/60Hz or 100–250V DC. The NF series also includes built-in surge protection, so a separate surge suppressor is generally not required. It is suitable for MCC panels, automation panels, interlocking circuits, PLC interface circuits, machine control, status indication and industrial switchboards.
