ABB 1SBH137001R1131

The NF contactor relay is engineered for auxiliary and control circuit switching, featuring an electronic coil interface that accommodates a broad control voltage spectrum. The relay can manage variations in control voltage without requiring coil changes, making it suitable for global applications. Notably, it has built-in surge protection, eliminating the need for external suppressors.

This model includes four poles and complies with IEC standards, featuring three normally open auxiliary contacts and one normally closed auxiliary contact. The device operates on both AC and DC control circuits. It is mounted on standard DIN rails with options for screw fastening. The relay's compact dimensions are 45 mm wide, 77 mm deep, and 86 mm high, weighing 0.27 kg.

With a rated operational voltage of 690 V for the auxiliary circuit and a rated frequency of 50/60 Hz, it supports a variety of operational currents. Its performance includes a maximum electrical switching frequency of 1200 cycles per hour for AC and 900 cycles per hour for DC, ensuring reliable operation in dynamic applications. The NF31E-11 is not suitable for direct control via PLC output and is available in select regions.
