Allen-Bradley 156-B30AB1 Phase Semiconductor Contactor is a 30 A single-phase solid-state contactor designed to switch AC non-motor loads in industrial control circuits. It accepts line voltage from 24–230 VAC (some listings extend to 240 VAC) and is driven by a 5–24 V DC control voltage, with an integrated varistor for surge protection. The 156-B series is intended for single-phase operation and carries a 30 A current rating; some retailer listings note it as discontinued.
