Square D 8911DPSO13V09 Definite Purpose Contactor 3P 20A

Product Description

The SQUARE D 8911DPSO13V09 is a three-pole definite purpose contactor rated for 20 amps of inductive load. It is designed for use in motor-control and HVAC applications where a reliable, code-rated switching device is required. The coil operates at 208 to 240 volts AC at 60 Hz and 220 volts AC at 50 Hz, making it suitable for standard North American single-phase and three-phase systems. The open enclosure design fits standard control panels and condenser unit wiring compartments. Licensed HVAC technicians and industrial electricians are the primary installers of this device.

This contactor is applied in residential and light commercial HVAC systems, including air conditioner condensing units, heat pumps, and motor-load circuits. It carries horsepower ratings across multiple voltages: 1.5 HP at 115 volts AC, 3 HP at 230 volts AC single-phase, and 7.5 HP at 230, 460, and 575 volts AC three-phase. These ratings make it a fit for compressor and fan motor control in split-system and packaged equipment.

Key Features

• Three-pole configuration supports both single-phase and three-phase motor loads
• 20-amp inductive load rating suitable for compressor and fan motor applications
• Coil rated for 208 to 240 volts AC at 60 Hz and 220 volts AC at 50 Hz
• Open enclosure design for panel and equipment cabinet installation
• Horsepower ratings span 115V through 575V for broad motor compatibility

Compatibility

Designed as an OEM-style definite purpose contactor for three-pole motor-load applications in HVAC condensing units and light commercial motor control circuits where a 208-240V coil and 20-amp inductive load rating are specified.

Installation Notes

Installation should be performed by a licensed electrician or HVAC technician in accordance with NEC requirements for motor branch circuits. De-energize and lock out the equipment before removing the existing contactor and before making any wire terminations. Verify coil voltage matches the control circuit before energizing. Confirm load-side wire gauge is rated for the full inductive load ampacity of the circuit.
