1SBH137001R1340

ABB NF40E-13 (1SBH137001R1340) is a 4-pole auxiliary contactor / contactor relay with four Normally Open contacts, designed for switching auxiliary and control circuits in industrial automation and electrical panels.

Its electronic coil accepts a wide 100–250V AC 50/60Hz or 100–250V DC control range. ABB states that NF contactor relays can handle large control-voltage variations and include integrated surge protection, so an additional surge suppressor is generally not required. Typical uses include MCC panels, PLC interface circuits, interlocking, machine automation, signaling and industrial control panels.
