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

Features and Benefits:

• 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

Applications

• 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

What standards validate the device’s ingress and electrical characteristics?

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

How many switching poles does it provide and how are they arranged?

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

What mounting orientation and connection method are required?

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

What voltage and current figures should installers consider for control circuits?

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.
