ABB Auxiliary Contact Block, 4 Contact, 1 NO/3 NC, 1SBN01, Front, 4 A, 690V, 1SBN010040R1213

This auxiliary contact Block provides supplementary switching contacts for control and signalling functions in industrial electrical assemblies. Designed for front mounting, it interfaces with primary switching devices to extend monitoring and interlock capabilities while operating within low-power control circuits.

• Four contacts combining one normally open and three normally closed for versatile logic arrangements
• Screw Terminal connection enabling secure field wiring and straightforward installation
• Rated for 4A switching current to manage small control loads reliably
• Operational current capability of 6A for defined control circuit performance
• Insulation rating of 690V to maintain separation in higher-voltage systems
• Mechanical endurance of 10M cycles supporting frequent actuation in automated systems

• Suitable for auxiliary signalling in motor control centres
• Ideal for interlock circuits in automation panels
• Used with contactors to expand contact configurations
• Can be used for status feedback to PLC inputs
• Suitable for retrofit front-mounting on existing control gear

It is intended for front mounting, allowing placement directly on the actuator Interface of compatible devices.

Connections are provided via screw terminals, facilitating solid conductor clamping and routine maintenance access.

The mix of one normally open and three normally closed contacts enables combined make/break functions for control and safety interlocks.

It conforms to IEC 60947-5-1 and also meets VDE and regional UL/CSA directives for its category.

With a 690V insulation rating and defined switching/current capacities, it is appropriate where higher insulation and modest control currents are required.
