The First Company E1511 is a 45 MFD (microfarad), 370-volt run capacitor engineered to deliver consistent, dependable performance in HVAC fan and compressor motor applications. Designed as an OEM-quality replacement, this capacitor helps maintain proper motor torque, reduces energy consumption, and extends the operational life of motors in air handlers, fan coils, and related HVAC equipment.
Key Features
- Capacitance: 45 MFD (µF)
- Voltage Rating: 370V AC
- OEM replacement part for First Company HVAC equipment
- Supports reliable motor starting and continuous run operation
- Helps maintain motor efficiency and reduce heat buildup
- Suitable for use in fan motors and compressor circuits
Application
This run capacitor is a direct replacement for First Company HVAC systems requiring a 45 MFD / 370V capacitor. It is commonly used in air handler units, fan coil units, and other motor-driven HVAC equipment where maintaining proper phase shift and motor torque is critical to system performance.
Why Replace a Failing Capacitor?
A worn or failed run capacitor can cause motors to run hot, draw excessive current, operate inefficiently, or fail to start altogether. Replacing a faulty capacitor promptly with the correct OEM-spec part like the E1511 helps prevent costly motor burnouts and system downtime.
