ABB 1SBN01 Series Auxiliary Contact Block, 4A Contact Current, Front Mount Type - 1SBN010042R1131

This auxiliary contact Block provides additional switching contacts for control circuits, designed for front mounting on contactors and similar devices. It offers a mix of normally open and normally closed contacts to extend signalling and interlock functions within automation and electrical installations, complying with recognised ingress and switchgear standards for industrial environments.

Features and Benefits:

• 3NO1NC contact arrangement enables versatile signalling options
• Four-pole configuration supports multi-circuit switching
• 4A contact rating permits low-power control loads
• 690V rated insulation suits high-voltage control circuits
• Screw terminals allow secure, conventional wiring connections
• Front-mount design simplifies retrofitting and panel access

Applications

• Suitable for extending contactor signalling in motor control panels
• Ideal for interlock functions in automation assemblies
• Used with control relays requiring additional auxiliary contacts
• Can be used for status feedback in electrical distribution gear
• Useful in retrofits where front-mounted accessories are required

What is the electrical endurance for frequent switching applications?

The contact Block is rated for continuous insulation at 690V and a contact current of 4A, making it appropriate for repetitive low-power control operations under specified switching cycles.

How is the unit attached to a primary device in an installation?

It is designed for front mounting, enabling direct attachment at the front of compatible contactors to add auxiliary contacts without altering the main device footprint.

Which standards relate to its environmental protection and switchgear compatibility?

It meets the referenced EN 60529 for ingress considerations and is specified in accordance with IEC 60947-1 for low-voltage switchgear requirements.

What Terminal type should installers expect when wiring control circuits?

Connections are MADE via screw terminals, permitting orthodox conductor termination and straightforward on-site wiring.

How many separate electrical circuits can be controlled simultaneously?

The Block provides four contacts in total, arranged to handle multiple signalling or interlock circuits in a Compact accessory.
