Why Choose the ABB 1SBH131001R8844 NFC44E-88 Contactor Relay?
The ABB 1SBH131001R8844, also known as the NFC44E-88, is an 8-pole AC-operated contactor relay designed for reliable switching of auxiliary and control circuits in industrial automation and electrical control systems. As part of the ABB NFC contactor relay range within the AF platform, it combines mechanically linked auxiliary contacts with optimised operating times for dependable AC-controlled applications.
The NFC44E-88 features 8 auxiliary contacts, comprising 4 normally open (N.O.) and 4 normally closed (N.C.) contacts. Its block-type construction provides a compact solution for control, interlocking, signalling and sequencing functions, while compatibility with ABB add-on auxiliary contact blocks and AF-platform accessories enables straightforward expansion where additional control functions are required.
Designed for an electromagnetic control coil rated at 230–240 V AC at 50 Hz or 240–260 V AC at 60 Hz, the NFC44E-88 integrates easily into industrial AC control circuits. With a 690 V IEC rated operational voltage, screw terminals and a compact 45 mm-wide housing, it is well suited to machinery, automation panels and industrial control equipment.
