Square D 8911DPSG23V09 Definite Purpose Contactor 3P 25A

Product Description

The SQUARE D 8911DPSG23V09 is a 3-pole definite purpose contactor rated for 25 amps of inductive load, designed for motor and load switching in commercial and industrial HVAC, refrigeration, and related electrical control applications. The coil operates at 208 to 240 volts AC at 60 Hz and 220 volts AC at 50 Hz, making it compatible with both North American and select international supply voltages. Housed in a NEMA 1 enclosed enclosure, it provides basic protection against incidental contact in indoor environments. Licensed electricians and HVAC-R technicians are the primary installers of this contactor in packaged and split commercial systems.

This contactor is suited for single-phase and three-phase motor load applications. Horsepower ratings include 2 HP at 115 volts AC, 5 HP and 10 HP at 230 volts AC, 15 HP at 460 volts AC, and 20 HP at 575 volts AC. These ratings cover a range of compressor, fan, and pump motor loads commonly found in light commercial HVAC equipment, refrigeration systems, and industrial control panels installed indoors.

• Horsepower ratings up to 20 HP at 575 volts AC for larger motor applications
• NEMA 1 enclosed enclosure for general-purpose indoor installation
• Definite purpose design optimized for HVAC-R and motor switching duty cycles

Compatibility

Designed as an OEM-style definite purpose contactor replacement for 3-pole, 25-amp inductive load applications in indoor HVAC, refrigeration, and motor control systems requiring a 208-240 volt AC coil.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC-R technician in accordance with the NEC and applicable local codes. Disconnect and lock out all power to the panel or equipment before removing the existing contactor or making any wiring connections. Verify coil voltage matches the control circuit supply before energizing. The NEMA 1 enclosure is rated for indoor use only and should not be installed in wet, outdoor, or corrosive environments without additional protection.
