POWER MONITORING & PROTECTION ACI CURRENT-OPERATED SWITCHES A/ACS, A/ASCS, A/CS, A/SCS, A/CR SERIES DESCRIPTION The ACI current switches are solid-state devices that operate when the sensed AC current level exceeds a fixed or adjustable trip point. The A/CS Series is solid-core with a fixed trip point. The A/SCS Series is split-core with a fixed trip point. The A/ACS Series is solid-core with adjustable trip point. The A/ASCS Series is split-core with adjustable trip point. All models monitor either a 0-200 or 0-250 amp current flow in the wire and are available in normally-open or normally-closed configurations. The A/CR Series command relay brings control to monitoring applications.
