1SBN010140R1022

ABB 1SBN010140R1022 – CA4-22E is a 4-pole front-mounted auxiliary contact block designed for compatible ABB AF contactors. It provides two normally open (2NO) and two normally closed (2NC) instantaneous auxiliary contacts, allowing several signaling, interlocking, control and feedback functions to be added to a contactor from a single accessory. The CA4-22E is intended for auxiliary and control circuits in standard industrial environments. It uses screw-type connecting terminals, delivered open and protected against accidental direct contact, with contact-function markings to simplify wiring and maintenance.
