Why Choose the ABB 1SBH131001R8453 NFC53E-84 Contactor Relay?
The ABB 1SBH131001R8453 (NFC53E-84) is a high-performance 8-pole contactor relay designed for switching auxiliary and control circuits in industrial automation, machine control and electrical panel applications. As part of the ABB NFC contactor relay range, it combines a compact block-type design with optimised operating times for AC-controlled applications.
The NFC53E-84 provides 5 normally open (NO) and 3 normally closed (NC) auxiliary contacts, giving eight mechanically linked contact elements for flexible control, signalling and interlocking functions. Its electromagnetic AC control system and screw terminal connections make it straightforward to integrate into conventional industrial control circuits, while compatible ABB AF platform accessories allow the relay configuration to be expanded when required.
With a rated control supply of 110 V AC at 50 Hz or 110–120 V AC at 60 Hz, the NFC53E-84 is suited to industrial systems using these common AC control voltages. The relay supports operational voltages up to 690 V AC under IEC ratings and offers a compact format of approximately 86 × 45 × 110.5 mm for efficient installation within control cabinets.

Reliable Switching for Industrial Control Circuits
Contactor relays such as the ABB NFC53E-84 provide electrically operated contacts for auxiliary and control circuits rather than primary motor power switching. Their multiple contacts can be used for electrical interlocking, control sequencing, signal multiplication, status indication and interface functions throughout industrial automation systems.
The NFC53E-84 combines five normally open and three normally closed mechanically linked contacts with an electromagnetic AC coil optimised for control applications. Its eight-pole block construction provides substantial switching flexibility from a single device, while compatibility with the wider ABB AF platform accessory range allows additional functionality to be incorporated where required.
Typical Applications
- Industrial control and automation panels.
- Electrical interlocking and sequencing circuits.
- Motor starter auxiliary control systems.
- Machine status and control signalling.
- PLC interface and signal multiplication circuits.
- OEM machinery and production equipment.
