The ABB CA5‑22E is a front‑mounted auxiliary contact block designed to expand the switching capability of ABB contactors in industrial control systems. It provides additional auxiliary contacts that can be used for control and signaling functions (such as status indication, interlocking, or control circuit feedback) separate from the main power contacts of a contactor. This accessory is compatible with a broad range of ABB A‑series and AF‑series contactors and is suitable for use in low‑voltage AC control circuits up to 690 V. Its compact, robust design makes it ideal for industrial electrical panels and automation setups
