ABB 2CCS800900R0011 S800-AUX Auxiliary Contact Block DIN-Rail Mount for S800 Series Circuit Breakers

The ABB S800-AUX (SKU: 2CCS800900R0011) is a DIN-rail mounted auxiliary contact block designed for use with ABB's S800 series miniature circuit breakers, providing essential status signalling and remote monitoring capability in industrial control panels and distribution boards. Compact at just 9 mm wide, the S800-AUX integrates directly alongside S800 series breakers to report open/closed switching states to control systems, PLCs, and supervisory equipment. Weighing only 50 g, it is engineered for panel-space efficiency without compromising reliability.
