Air Compressor Application
Schneider Electric specifically identifies air compressors as an intended application for the Class 8911 DPS starter family. The exact 8911DPSG43V09 is a 40A enclosed three-phase starter rated by Schneider for 10 HP at 230V, making it a common configuration for 10 HP 208–230V three-phase compressor packages.
Overload Heater Selection
This 40A DPSG starter uses Square D B-series thermal units. Heater selection must be based on the motor's actual nameplate full-load current (FLA), not horsepower alone.
Recommended Heater Inserts
B-36 — 22.6–26.2A for an enclosed DPSG43 three-phase starter
B-40 — 26.3–28.0A for an enclosed DPSG43 three-phase starter
Three matching B-series thermal units are required. Verify the motor's actual nameplate FLA before ordering heaters.
