Single Run Capacitor, Round, 25/370 uF

Mars 12715 – JARD 25 MFD 370V Round Motor Run Capacitor

The Mars 12715 is a single-value motor run capacitor with a capacitance of 25 microfarads (MFD) and a voltage rating of 370 VAC. Designed for use in permanent split capacitor (PSC) single-phase motors, it supports continuous-duty operation in HVAC fan motors and other inductive loads. This round capacitor is part of the JARD by Mars line and conforms to EIA-456-A performance and safety standards.

Constructed with a rolled aluminum shell and oil-filled non-PCB dielectric, the 12715 includes a pressure-sensitive internal interrupter to disable the unit in the event of an internal fault. The unit is UL-recognized for use in air conditioning and refrigeration systems operating on 50/60 Hz service.
