ABB Auxiliary Contact Block, 4 Contact, 2 NC/2 NO, 1SBN01, Front, 4 A, 690V, 1SBN010042R1122

This auxiliary contact Block provides additional signalling and interlock contacts for control systems in industrial settings. Designed for front mounting, it interfaces with contactors and control modules to extend switching capabilities while maintaining compatibility with standard control voltages and currents.

• Four contact poles offering mixed normally closed and open contacts for versatile signalling
• Rated for 690V to handle high-voltage control circuits safely
• 4A contact current supports modest auxiliary switching loads
• Screw terminals ensure secure electrical connections in installations
• Front-mount configuration simplifies retrofitting to existing equipment
• UL and CSA approvals enable use in certified industrial installations

• Suitable for adding auxiliary contacts to motor starter assemblies
• Ideal for status feedback loops in automation panels
• Used with control relays to expand contact capacity
• Can be used for interlock signalling in manufacturing machinery
• Suitable for electrical panels requiring certified auxiliary switching

It offers four contacts arranged as two normally closed and two normally open for combined monitoring and control functions.

The unit uses screw-type terminals to secure conductors and accommodate typical panel wiring practices.

The auxiliary contact Block is specified with an operational current of 2A for control circuitry while the contact current capacity is 4A for switching loads.

It is designed for front mounting, allowing attachment to the accessible face of contactors or control modules for straightforward access and wiring.
