Schneider Electric Square D 8910LO4 Contactor

Schneider Electric’s Square D 8910LO4 Contactor is a 8910-series definite-purpose device with a 120 VAC coil, built to switch motor loads in HVAC, refrigeration, and related equipment. The 8910 family supports 2-pole and 3-pole configurations with current ratings ranging from 20 to 90 A, enabling use across a broad range of AC-1 motor control applications. In 120 VAC coil variants such as the 8910DPA33V02, a 3-pole model provides 30 A full-load current with three normally open contacts and operates on 50/60 Hz, making it suitable for compressor, fan, and pump control. Typical life is rated around 500,000 operating cycles, and compact housing measures roughly 50.8 mm by 62.2 mm by 84.3 mm, aiding installation in panel-mounted control enclosures. Coil voltage for these devices commonly covers 110–120 VAC at 50/60 Hz, with 120 V coils represented in the coil-code catalog by suffixes like V02, helping ensure compatibility with standard control circuitry.
