Square D 8911DPSG13V02 Definite Purpose Contactor 3P 20A

Product Description

The SQUARE D 8911DPSG13V02 is a 3-pole definite purpose contactor rated for 20 amps of inductive load and designed for reliable switching in HVAC, refrigeration, and light commercial motor control applications. The coil operates at 110 coil VAC at 50 Hz and 120 coil VAC at 60 Hz, making it compatible with standard North American and international supply voltages. It ships in an enclosed NEMA 1 configuration, providing basic protection against contact with live parts in indoor, non-condensing environments. Licensed electricians and HVAC technicians are the primary installers of this device in motor control and compressor circuits.

This contactor is suited for single-phase and three-phase motor loads across a range of horsepower ratings. Rated horsepower performance includes 1.5 HP at 115 VAC single-phase, 3 HP at 230 VAC single-phase, 7.5 HP at 230 VAC three-phase, 7.5 HP at 460 VAC three-phase, and 7.5 HP at 575 VAC three-phase. Typical installations include rooftop units, condensing units, air handlers, chillers, and packaged commercial HVAC equipment where a definite purpose switching device is required by the equipment manufacturer or design engineer.

Compatibility

Designed as an OEM-style definite purpose contactor for single-phase and three-phase HVAC, refrigeration, and motor control equipment requiring a 3-pole, 20-amp, 120 coil VAC switching device in a NEMA 1 enclosed package.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with the National Electrical Code (NEC) and all applicable local codes. Disconnect and lock out all power to the circuit before removing the existing contactor or making any wiring connections. Verify that supply voltage, coil voltage, pole count, and amperage rating match the equipment nameplate before energizing. Do not exceed the contactor rated load current or apply it outside its listed enclosure type.
