The ABB CA5-10 is a front-mounting auxiliary contact block designed to expand the functionality of ABB A-line contactors and N-series contactor relays. This accessory easily snaps onto the front face of the contactor, providing an additional normally open (1NO) contact for use in control and signaling circuits. Built with high-quality materials, the CA5-10 ensures reliable performance and secure connections thanks to its screw-type terminals. It is an essential component for creating more complex logic in industrial control panels, motor starters, and automation systems, offering a simple and effective way to add auxiliary contacts without requiring additional panel space.
