ABB 1SBN010140R1022

CA4-10 Auxiliary Contact Block

The 1SBN010140R1022 is a front-mount auxiliary contact block from ABB, type CA4-10, designed to snap onto A –line contactors (A/AF series) to add an auxiliary signalling contact. It provides one instantaneous normally-open contact that mirrors the state of the main contactor for status feedback, interlocking and control-circuit duties.

The block mounts directly on the front of the contactor and is wired through screw terminals, keeping the assembly compact and the wiring straightforward. It is rated for auxiliary-circuit switching to IEC/EN 60947-5-1 and is a standard accessory in ABB’s contactor system.

Use it to expand the auxiliary contact count of A/AF contactors in motor starters, control panels and automation cabinets where additional status or interlock signals are required.
