Allen-Bradley 156-B25CA2 is a dual-phase solid-state semiconductor contactor from the 156-B series, rated for 25 A and capable of switching up to 600 VAC on the load side. The control coil accepts 24–275 VAC or 24–190 VDC signals, allowing flexible interfacing with AC or DC control circuits; the load line voltage range is 48–660 VAC. This device is intended for non-motor loads such as heating elements or lighting circuits, where reliable, quiet switching is required.
