ABB Auxiliary Contact Block, 4 Contact, 3 NO/1 NC, Contact Block, Front, 6 A, 690V, 1SBN010140R1131

This auxiliary contact Block provides additional switching contacts for control circuits in industrial electrical systems, mounted at the front of equipment to extend signalling and interlock functionality. It is designed for integration with motor starters and contactor assemblies where compact, front-accessed auxiliary contacts are required.

• 4P configuration offering three normally open and one normally closed contact for versatile interlocking
• Rated for 6 A operational current to manage auxiliary circuit loads effectively
• 690 V-rated insulation voltage to suit high-voltage control environments
• Screw terminals enabling secure conductor connections and straightforward wiring
• Mechanical life of 3,600 cycles reducing maintenance intervals in repetitive operations
• Conforms to IEC 60947-5-1 for compatibility with standard control gear requirements

• Suitable for extending contactor functionality in motor starters
• Ideal for status signalling in automation control panels
• Used with DIN rail-mounted contactors in industrial switchgear
• Can be used for interlock circuits in machinery safety arrangements

It is front-mounted to fit on the front of compatible control devices, allowing access without rear clearance.

Screw terminals permit firm clamping of conductors and are compatible with common ferrules and stranded cable techniques.

It holds multiple approvals across international standards including IEC 60947-1 and EN 60529 classifications, supporting use in regulated installations.

The Block provides four contacts arranged as three normally open and one normally closed to support both signalling and interlocking functions.
