ABB 1SBN01 Series Auxiliary Contact Block, 4 NO Normal State Configuration, 4A Contact Current - 1SBN010042R1240

This auxiliary contact Block is an add-on switching device designed to extend the signalling and control capability of contactors in industrial electrical panels. It mounts to the front of compatible gear and provides additional changeover contacts for monitoring and interlocking tasks within automation and electrical systems.

Features and Benefits:

• Four normally open contacts providing expanded control capacity
• Screw Terminal connections allowing secure conductor attachment
• Rated for switching up to 4A to handle signalling loads
• Insulation rated to 690V for high-voltage separation requirements
• Front mounting for straightforward installation on contactors
• Complies with IEC and EN enclosure and switchgear standards

Applications

• Suitable for status feedback to PLCs and control systems
• Ideal for interlock circuits in motor control centres
• Used with contactors to increase auxiliary contact count
• Can be used for alarm or indication circuits in switchgear
• Suitable for retrofit additions on front-mounted control assemblies

What is the appropriate use for the block’s current capability?

It is intended for small switching and signalling duties where contact currents do not exceed 4 A and where control circuits require low-power switching.

How is the component secured electrically to the control wiring?

Electrical connections are MADE via threaded screw terminals that ensure a clamp-type contact on conductors for consistent electrical continuity.

What operational current should be considered for persistent switching?

Continuous operational considerations should be based around a typical operational current rating of 2 A for repeated actuation cycles.

Which environmental protection and standardisation parameters does it meet?

The device aligns with international enclosure and low-voltage switchgear standards including IEC 60529 and IEC 60947-1 as well as the relevant EN directive for ingress classification.

How many poles does the unit provide and how does that affect circuit design?

It provides four poles, enabling independent switching of up to four separate circuits for expanded control or signalling functionality.
