Square D 8910DPA34V02U1 Definite Purpose Contactor 4P 30A

Product Description

The SQUARE D 8910DPA34V02U1 is a 4-pole definite purpose contactor rated for 30 amps on inductive loads and 40 amps on resistive loads. Definite purpose contactors are designed for specific switching applications in HVAC, refrigeration, and light commercial equipment where general-purpose contactors would be oversized or impractical. This unit provides reliable load switching for compressors, condenser fan motors, and similar inductive equipment. Licensed HVAC technicians and electricians typically install this type of contactor during equipment repair or scheduled component replacement. The 4-pole configuration allows switching of multiple circuits simultaneously in a compact footprint measuring 4.2 inches in length, 3.3 inches in width, and 3.3 inches in height.

This contactor is suited for residential and light commercial HVAC and refrigeration systems where a definite purpose switching device is required. Typical installation scenarios include rooftop units, split-system condensing units, refrigeration compressor circuits, and similar equipment that draws inductive current at startup. The 30 amp inductive and 40 amp resistive ratings cover the load profiles common in these applications. It is packaged and sold as a single unit, making it appropriate for individual service calls and one-for-one replacement work.

Key Features

• 4-pole design switches multiple circuits in a single operation
• 30 amp inductive load rating suitable for motor and compressor circuits
• 40 amp resistive load rating for broader application flexibility
• Compact body at 4.2 x 3.3 x 3.3 inches fits standard contactor mounting locations
• Definite purpose design optimized for HVAC and refrigeration duty cycles

Compatibility

Designed as an OEM-style definite purpose replacement contactor for residential and light commercial HVAC, refrigeration, and motor control applications requiring a 4-pole, 30 amp inductive rated switching device.

Installation Notes

Installation should be performed by a licensed electrician or HVAC technician in accordance with the National Electrical Code (NEC) and applicable local codes. Disconnect and lock out all power to the unit before removing the existing contactor or handling line-side wiring. Verify that the replacement contactor coil voltage matches the control circuit voltage of the equipment before energizing. Do not exceed the rated inductive or resistive load values marked on the device.
