The ABB S2C-H11R is a compact, ice-cube type general-purpose plug-in relay from ABB's broad range of industrial control relays. It belongs to a family known for their standardized "ice cube" or "square base" form factor. This specific model features a single-pole, double-throw (SPDT or "Form C") contact configuration and is designed for low-power switching in control panels, machinery, and automation systems. The suffix "H11R" typically denotes a specific coil voltage and contact arrangement.
