ABB Auxiliary Contact, 2 Contact, 1 NO/1 NC, Cat4, Front, 6 A, 600 V dc, 690V ac, 1SBN010151R1311 CAT4-11U

This auxiliary contact provides supplementary switching capability for control and signalling circuits in industrial installations. It is designed for front-side mounting and connects using screw terminals, offering a Compact solution for adding two auxiliary contacts to a primary device. The unit supports common automation and electrical control tasks where additional feedback or interlocking is required.

• 6 A switching current supports low-power control circuits
• 690V insulation rating enables high-voltage application compatibility
• 1 NO/1 NC arrangement offers versatile signalling combinations
• 2 P contact configuration allows independent dual-circuit control
• -40 °C to 70 °C operating range suits harsh environmental conditions
• Mechanical endurance of 10 M cycles minimises maintenance intervals

• Suitable for feedback circuits in motor control panels
• Ideal for interlock signalling in industrial automation systems
• Used with contactors to expand auxiliary contact capacity
• Can be used for status indication on switchgear door systems

Connections are via screw terminals that secure conductors for reliable contact in control panels.

The single normally open and normally closed contacts permit one signal and one interlock connection without additional relays.

The device is intended for front mounting, locating the contact on the front side of the host equipment for easy access.

It is specified for both AC and DC use up to a contact voltage of 600V DC and 690V AC, suitable for a range of industrial circuits.
