MARS 12816 Run Capacitor

When you're out on a service call and find a condenser fan motor or compressor struggling to turn over, the MARS 12816 (Jard) is the reliable dual run capacitor replacement you need in your truck. This 80/7.5 MFD 440V round capacitor is engineered for high-performance HVAC motor support, providing critical phase shift for both the compressor and the fan. Designed for continuous duty, it features a 440 VAC rating—allowing it to safely replace older 370V units—and is housed in a rugged, non-PCB, oil-filled aluminum case. With a temperature range of -40°C to +70°C and a built-in pressure sensitive interrupter (PSI) for safety, this unit handles high ambient loads and 50/60 Hz frequencies without breaking a sweat. Standard 1/4-inch male quick-connect terminals ensure you aren't wasting time on AC capacitor replacement in the field, making it a direct-fit solution for residential air conditioning and light commercial systems.

• Dual Capacitance: Consolidates 80 microfarads for the compressor and 7.5 microfarads for the fan motor into a single, space-saving round profile.
• High Voltage Compatibility: Rated at 440V, making it a durable choice for systems requiring either 370V or 440V protection.
• Industrial Build: Features a metallized polypropylene film and a sealed aluminum shell to withstand heavy vibration and extreme outdoor heat.
• Safety Integrated: Equipped with a patented internal pressure interrupter designed to disconnect the capacitor in the event of failure.
• Universal Standards: Meets UL and CSA approvals, ensuring it matches OEM specifications for technical compliance.

Can I use this 440V capacitor to replace a 370V unit?
Yes. You can always go up in voltage rating, but never down. Using a 440V capacitor where a 370V was originally installed provides a higher safety margin against voltage spikes.

What happens if the microfarad (MFD) rating doesn't match?
Installing a capacitor with the wrong MFD rating can lead to excessive heat and internal motor damage. Always match the 80/7.5 MFD rating exactly as specified by the equipment manufacturer.

Why is the top of my old capacitor bulged?
A bulged top indicates the internal pressure interrupter has tripped due to overheating or an electrical fault. This is a clear sign the unit needs immediate replacement.
