ALLEN-BRADLEY 509-DOD-XXX SER A SIZE 3 FULL VOLTAGE MOTOR STARTER WITH 592-EEGD OVERLOAD RELAY

ALLEN-BRADLEY 509-DOD-XXX SER A SIZE 3 is a classic NEMA Size 3 three-phase full voltage non-reversing motor starter, equipped with integrated 3-pole magnetic contactor and matched 592-EEGD eutectic alloy thermal overload relay, rated 90A, control coil 120V. This NEMA motor starter assembly is used for remote on-off control of three-phase AC motors and provides motor overload protection. This NEMA motor starter assembly adopts high-performance silver alloy main contacts for repeated heavy-current switching. This NEMA motor starter assembly is open-type construction, designed for rack installation inside industrial power control cabinets.

This unit is a vital industrial motor control spare part for factory machinery overhaul. The industrial motor control spare part uses 120VAC coil to pull in or release the main contactor remotely. The industrial motor control spare part works with 592-EEGD thermal relay to monitor motor operating current and trip under overload condition. The industrial motor control spare part includes auxiliary contacts for status feedback and interlock logic. The industrial motor control spare part can replace the defective starter assembly to restore motor start-stop and overload protection.

It delivers reliable motor full-voltage power switching control for industrial automation systems. The motor full-voltage power switching control connects main power circuit to motor when coil energized. The motor full-voltage power switching control cuts off power automatically when overload current occurs. The motor full-voltage power switching control withstands large motor starting inrush current for pumps, conveyors and fans.

ALLEN-BRADLEY 509-DOD series NEMA Size 3 starter is widely installed in industrial power panels for general three-phase motor control. It is legacy Rockwell Allen‑Bradley DOL direct-on-line starter with thermal overload relay.
