Allen-Bradley 700-P400A1 AC Relay 600VAC 10A NEMA

The Allen-Bradley 700-P400A1 is a four-pole, NEMA heavy-duty industrial control relay designed for electromechanical switching of AC control circuits in industrial automation. It provides 4 normally open contacts with a 10 A continuous rating at 600 VAC and a maximum switching voltage of 600 VAC, using silver-nickel contacts for dependable operation. The coil accepts 110 VAC (50 Hz) or 115–120 VAC (60 Hz), and the unit mounts on a DIN rail or by screw/panel in an open enclosure as part of Bulletin 700-P. Common applications include control panels, motor control centers, HVAC equipment, conveyors, and pumps, with common replacements including Allen-Bradley 700-PK400A1 and 700-N400A1 relays.
