Oil Cap 45UF

Description

45uF 450V AC CBB65 Metallized Polypropylene Film Capacitor The CBB65 is an industry-standard, heavy-duty motor run capacitor housed in a rugged, hermetically sealed aluminum casing. Filled with eco-friendly protective oil, this cylinder-style capacitor is engineered for excellent heat dissipation and reliable continuous operation. It stabilizes the voltage and current phase shifts required for demanding alternating current (AC) motors to run efficiently. Key Specifications Capacitance: 45 uF (Microfarads) ± 5% Voltage Rating: 450V AC (Also safely replaces 370V AC models) Frequency: 50/60 Hz Build Type: CBB65 Round Aluminum Can (Oil-filled, typically features standard 1/4-inch quick-connect terminals) Safety Feature: Internal explosion-proof pressure disconnector Supported Machinery & Equipment A 45uF capacitor is a high-capacity component most commonly found in heavy-duty climate control and industrial motor machinery: 1. Air Conditioning Systems (HVAC) Central Air Units & Heat Pumps: This is primarily used as a compressor run capacitor for large residential and commercial air conditioning condensing units (typically ranging from 2.5 to 3.5-ton systems). It helps the compressor motor maintain proper running torque. 2. Large Industrial Air Compressors Application: Supports the heavy electric motors used to power workshop air compressors, facilitating a smooth run cycle and preventing motor stalling under maximum tank pressure. 3. High-Power Water & Well Pumps Application: Utilized in high-flow centrifugal irrigation pumps, commercial well pumps, and multi-stage pressure booster pump motors to handle heavy starting loads and keep running temperatures low. 4. Portable Power Generators Application: Found in the regulation circuitry of mid-to-large-scale portable gasoline or diesel generators (often between 5kW and 8kW units) to help balance alternator fields and regulate power output. Tech Tip: If you are replacing a dual-section capacitor (which has three sets of terminals labeled Herm, Fan, and C), a single-value 45uF capacitor like this can still be used to run the compressor alone, provided a separate smaller capacitor is used for the fan motor.
