DiversiTech 37150H Run Capacitor

The DiversiTech 37150H is a professional-grade 15 MFD 370V oval run capacitor engineered for continuous duty in residential and commercial HVACR systems. Designed to stabilize current flow to single-phase induction motors, this component ensures consistent torque and optimal efficiency for condensing unit fan motors and small compressor start-up applications. Built with high-grade metallized polypropylene film and housed in a rugged aluminum casing, the 37150H is oil-filled to provide superior heat dissipation and internal pressure protection. This unit replaces standard 15 microfarad capacitors rated for 370 Volts, making it a staple for service vans. With standard ¼-inch male quick-connect terminals, it facilitates rapid field installation and secure electrical connections. The non-PCB oil construction meets modern environmental standards while maintaining dielectric strength under high-temperature conditions common in rooftop units and outdoor enclosures.

Technical Specifications & Key Benefits:

• Capacitance Rating: 15 MFD (microfarads) for precise motor phase shifting.
• Voltage Compatibility: Rated for up to 370 VAC; suitable for 208/230V systems.
• Form Factor: Space-saving oval run capacitor design for tight motor control boxes.
• Termination: Dual 4-blade terminals allow for simplified wiring of fan and common leads.
• Temperature Range: Engineered for an operating range of -40°C to +70°C.
• Safety Standards: Internal pressure interrupter designed to disconnect the capacitor in the event of an internal failure.

Common Contractor Questions:

Can I use a 440V capacitor to replace this 370V 15 MFD model?
Yes, a 440V capacitor can safely replace a 370V unit as long as the microfarad rating (15 MFD) remains identical. The voltage rating indicates the maximum threshold the dielectric can handle.

What are the symptoms of a failing 15 MFD capacitor in an AC system?
Common signs include a humming motor that fails to start, excessive heat at the motor housing, or a "bulged" top on the capacitor casing indicating the pressure interrupter has tripped.

Is this DiversiTech capacitor compatible with multi-tap motors?
The 37150H is compatible with any motor requiring a 15 MFD 370V rating, including PSC (Permanent Split Capacitor) motors found in various blowers and fans.
