ABB NF40E-12 (1SBH137001R1240) is a 4-pole auxiliary contactor / contactor relay with four Normally Open contacts. It is designed for switching auxiliary and control circuits in industrial automation, MCC panels, motor control systems, electrical interlocking, machine control and signalling applications.

The NF40E-12 uses ABB’s electronic wide-range coil technology, allowing operation over 48–130V AC 50/60Hz and 48–130V DC. ABB’s NF contactor relays also have integrated surge protection, reducing the need for a separate external surge suppressor.
