ABB Auxiliary Contact, 2 Contact, 1 NO/1 NC, Cat4, Front, 6 A, 600 V dc, 690V ac, 1SBN010151R1011 CAT4-11E

This auxiliary contact provides a Compact 2-pole front-mounted switching Interface designed for integration with AF contactors in industrial control systems. It offers instantaneous changeover functionality with both one normally open and one normally closed contact, and front-facing screw terminals for straightforward wiring. The unit is specified for auxiliary circuits up to 690V and is intended for standard industrial environments where an add-on contact Block is required.

• 6A operational current gives reliable control signalling
• 690V rated insulation supports high-voltage auxiliary circuits
• 10M cycles mechanical durability reduces maintenance frequency
• Front-mount screw terminals enable Rapid installation
• Operates from −40°C to 60°C for wide ambient ranges
• IEC, UL and CSA compliance ensures recognised design standards

• Suitable for status feedback on AF contactors in switchboards
• Ideal for control-panel interlocking and safety circuits
• Used with motor starters to signal auxiliary conditions
• Can be used for PLC input signalling in automation racks
• Suitable for retrofit replacement in AF series assemblies

Connections are MADE via screw terminals that accept a range of flexible and rigid conductor sizes including ferrules to match typical control wiring practices.

It contains one normally open and one normally closed instantaneous contact, providing complementary signalling outputs for control systems.

The unit has a rated impulse withstand of 6kV and defined short-time withstand currents for brief fault conditions.

The Block accepts flexible and rigid conductors from 0.75mm² up to 2.5mm², with specific ferrule configurations for multi-core terminations.

The contact Block is designed for front-side mounting so it mates directly with compatible AF contactor housings.
