- Trusted Mars quality — a leading name in HVAC electrical components
Typical Applications
- Residential and light-commercial air conditioning compressors
- Heat pump compressor motors
- Refrigeration unit motors requiring start-capacitor assistance
- Single-phase PSC and CSCR motor circuits
Installation Notes
Start capacitors are only in the circuit during motor start-up and are switched out once the motor reaches operating speed. Always discharge capacitors before handling and verify that the replacement capacitor’s µF range and voltage rating meet or exceed the OEM specification. Consult the equipment nameplate and wiring diagram before installation.
