Allen-Bradley 700-P400A1 AC Relay

The Allen-Bradley 700-P400A1 AC Relay is a NEMA heavy-duty industrial control relay from Rockwell Automation’s Bulletin 700-P series, designed for electromechanical switching of industrial control circuits in automation and motor-control applications. It has four normally open contacts, rated 10 A at 600 VAC (continuous), with coil options of 110 VAC at 50 Hz or 115–120 VAC at 60 Hz, and uses silver-nickel contact material in an open enclosure that can be mounted on a DIN rail or screwed to a panel, with a maximum rated voltage of 600 VAC. Commonly installed in control panels, motor control centers, machine tools, conveyors, pumps, and compressors, the 700-P400A1 supports interlocking and sequencing via its four N.O. contacts; for replacement options, consider Allen-Bradley 700-PK400A1 (20 A version), 700-N400A1, or another 700-P400A1 with matching coil voltage.
