ABB Auxiliary Contact Block, 2 Contact, 1 NO/1 NC, CAL4, Side, 6 A, 690V, 1SBN010120T1011 CAL4-11-T

This auxiliary contact Block is an add-on switching unit designed to extend control and signalling functions for contactors in industrial electrical systems. It provides an additional changeover contact set mounted on the side of the host device to monitor or interlock circuits in automation and control panels.

• 2P configuration supplies both normally open and normally closed contacts
• 6A operational current supports low-power control circuits
• 690V rated insulation suits high-voltage control environments
• Screw terminals enable secure wiring and straightforward maintenance
• Mechanical durability of 3600 cycles ensures long service intervals
• Side mounting format allows Compact installation on contactors

• Suitable for monitoring contactor status in motor control centres
• Ideal for interlock logic in industrial automation systems
• Used with auxiliary circuits for signalling and indicator lamps
• Can be used for sequence control in relay-based panels

It is designed for side mounting and connects directly to the contactor’s side interface, aligning its contacts with the host’s auxiliary connection points for integrated operation.

Terminals are screw type, allowing conductor fixation with standard tools and providing a reliable clamped connection suitable for routine panel wiring practices.

The internal insulation is rated at 690V, which permits use within elevated control-voltage environments provided the overall system design conforms to applicable electrical practices.

The unit presents one normally open and one normally closed contact in a two-pole arrangement, enabling both make and break functions for simple control schemes.
