ABB Auxiliary Contact Block, 4 Contact, 3 NO/1 NC, 1SBN01, Front, 4 A, 690V, 1SBN010040R1331

This auxiliary contact Block provides auxiliary signalling and control switching for industrial control equipment, designed for front mounting in panel or contactor assemblies. It is intended to extend the switching capability of primary devices by offering multiple auxiliary contacts suitable for monitoring and interlocking functions in electrical and automation systems.

• Four contacts configured as three normally open and one normally closed for versatile logic
• Rated insulation voltage 600V for higher withstand in control circuits
• Contact current capacity 4A to handle auxiliary loads reliably
• Operational current rated at 6A to support intermittent switching demands
• Screw terminals for secure conductor connection and straightforward installation
• Front mounting format for direct attachment to compatible devices without rear access

• Suitable for signalling auxiliary states in contactor control panels
• Ideal for interlock circuits in automation systems
• Used with motor starters to provide status feedback to PLCs
• Can be used for auxiliary switching in switchgear assemblies
• Used for remote indication and safety control circuits

It conforms to IEC 60529 for enclosure-related ratings and to IEC 60947-1 for low-voltage switchgear requirements.

It supplies four switching poles arranged to give three normally open contacts and one normally closed contact for mixed logic needs.

The unit is designed for front mounting and uses screw-type terminals for conductor attachment.

Consider an insulation rating of 600V, a contact current of 4A and an operational current capability of 6A when specifying for control and signalling loads.
