Square D 8911DPSG33V09 Definite Purpose Contactor 3P 30A

Product Description

The SQUARE D 8911DPSG33V09 is a 3-pole definite purpose contactor rated for 30 amps of inductive load. It is designed for use in motor control and load-switching applications across HVAC, refrigeration, and light commercial equipment. The coil operates at 208 to 240 volts AC at 60 Hz and 220 volts AC at 50 Hz, making it suitable for both domestic and international equipment configurations. It ships in an enclosed NEMA 1 enclosure. Licensed electricians and HVAC technicians install this contactor as part of compressor circuits, fan motor circuits, and other definite purpose motor loads requiring reliable switching performance.

This contactor is suited for single-phase and three-phase motor applications. Rated horsepower capacities include 2 HP at 115 volts AC, 5 HP at 230 volts AC, 10 HP at 230 volts AC, 15 HP at 460 volts AC, and 20 HP at 575 volts AC. It is commonly installed in commercial HVAC systems, condensing units, chillers, and refrigeration compressor panels where a robust definite purpose switching device is required.
