ABB 1SBH137001R1431

The NF31E-14 contactor relay is engineered for auxiliary and control circuit applications. It features an electronic coil interface that accommodates control voltages from 24 to 500 V across 50/60 Hz and DC, allowing a single coil to function with various global control standards without requiring a coil change. This relay supports large voltage variations, ensuring flexibility in operation.

With a robust design, it includes built-in surge protection, negating the need for external suppressors. This model includes 3 normally open (NO) and 1 normally closed (NC) auxiliary contacts, adhering to IEC standards for safety and reliability.

Dimensions of the product are 45 mm in width, 77 mm in depth, and 86 mm in height, with a weight of 0.31 kg. The relay operates effectively under various environmental conditions, with a permissible ambient temperature range from -40 to +70 °C and a maximum operating altitude of 3000 meters without derating.

Compliance with multiple standards such as IEC/EN 60947-1, IEC/EN 60947-5-1, UL 508, and CSA C22.2 No. 14-13 ensures that this device meets high safety and performance criteria. The NF31E-14 contactor relay also guarantees high switching frequencies, rated short-time withstand currents, and operational currents suitable for diverse industrial applications.
