Square D 8911DPSG13V09 Definite Purpose Contactor 3P 20A

Product Description

The SQUARE D 8911DPSG13V09 is a 3-pole definite purpose contactor rated for 20 amps inductive load, designed for use in motor control and HVAC switching applications. 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. It ships in a NEMA 1 enclosed housing, measuring 11.2 inches in length, 6.9 inches in width, and 6.4 inches in height, and weighs 5.69 pounds. Licensed electricians and HVAC technicians are the primary installers for this type of switching device.

This contactor is rated for single-phase and three-phase motor loads across a range of voltages. Horsepower ratings include 1.5 HP at 115 volts AC, 3 HP at 230 volts AC, 7.5 HP at 230 volts AC, 7.5 HP at 460 volts AC, and 7.5 HP at 575 volts AC. These ratings make it appropriate for compressor contactors, fan motor circuits, pump controls, and similar definite purpose switching loads found in commercial and residential HVAC, refrigeration, and light industrial systems.
