Schneider Electric 8910HO-4 Definite Purpose Contactor

Schneider Electric's Square D 8910HO-4 Definite Purpose Contactor is a four-pole device in the 8910 Definite Purpose Contactor family, designed for motor control in HVAC and refrigeration equipment where starting and stopping occur with defined frequency. As part of the 8910 class, these contactors are intended for definite-purpose applications and are aligned with ARI standards for heating, air conditioning, and refrigeration equipment. Current ratings for 8910 devices range from 20 A up to 90 A, with the HO-4 variant representing a 4-pole configuration within the family. Typical applications include compressor motors in air conditioning systems, refrigeration equipment, and other loads requiring reliable switching in HVAC duty. Coil voltage options vary by coil code; for example, some 8910DPA variants use a 277 VAC, 60 Hz coil, illustrating the range of available control voltages for this family. This model is documented in Schneider Electric’s official Square D 8910 Definite Purpose Control Contactor lineup and is described as a four-pole device suitable for HVAC and refrigeration applications.
