Hartland Controls CAP-55/440R Run Capacitor Look for signs of leakage

Look for signs of leakage at the actuator housing

this round dual run capacitor features a robust aluminum casing and 1/4" quick-connect terminals clearly labeled for Common (C)

also identified by part number X22440B7B

Using a fast-acting fuse in place of a slow-blow fuse will lead to frequent failures because it cannot withstand the initial inrush current of the boiler’s internal components

maintaining accurate calibration from -40°F to 120°F

Hartland Controls CAP-55/440R Run Capacitor Look for signs of leakageWhen you're out on a service call and find a dead compressor or fan motor that won't kick over, checking the run capacitor is your first move. The Hartland Controls CAP 55 440R is a heavy duty 55 MFD round run capacitor engineered for consistent performance in demanding HVACR environments. This 55 microfarad 440V capacitor is a versatile bench staple, as the 440VAC rating allows it to safely replace 370V units, providing a higher dielectric strength
