Schneider Electric PD311E Industrial Contactor

Schneider Electric's Square D PD311E industrial contactor is part of the 8502 family, a compact control device designed to switch electrical loads in industrial automation and motor-control panels. The PD311E model features a coil rated for 110 to 120 VAC, enabling straightforward integration with standard control circuits and relays without the need for additional interface components. As a representative of the 8502 series, it is intended for reliable actuation of inductive loads in applications such as pumps, conveyors, fans, and other equipment where remote energization from a 110–120 VAC supply is required. When paired with compatible Square D accessories and enclosures, the PD311E supports standard control wiring practices and helps create safe, organized motor-control configurations in industrial environments.
