Run Start Capacitor, Round, 50/10 MFD, 440/370

Mars 12892 Dual Run Capacitor – 50/10 MFD, 440/370V, Round The Mars 12892 is a dual-value run capacitor designed for continuous-duty applications in HVAC systems. With a capacitance of 50/10 microfarads and a voltage rating of 440/370V AC, it supports both compressor and fan motor operation within a single enclosure. This capacitor features metallized polypropylene film construction with an aluminum case and is internally protected by a pressure-sensitive interrupter. Its round profile and standard terminal layout allow for straightforward replacement in units requiring a compact dual-section capacitor. Technical Specifications: Model: Mars 12892 Capacitance: 50/10 MFD (μF) Voltage Rating: 440/370V AC Shape: Round Frequency: 50/60 Hz Terminals: ¼" quick-connect Operating Temperature Range: -40°C to +70°C Construction: Metallized polypropylene, aluminum can Safety Features: Pressure-sensitive internal interrupter Certification: UL recognized Application & Use: Designed for use in permanent split capacitor (PSC) motor applications. Supports dual motor systems—typically condenser fan and compressor units—in packaged or split HVAC systems. Suitable for use in equipment that specifies a 50/10 MFD capacitor with a 370V or 440V rating. Installation Guidelines: De-energize all circuits before service. Confirm proper discharge of existing capacitor. Verify rating matches equipment requirements before installation. Install in accordance with applicable electrical codes and manufacturer specifications. Professional installation is recommended to ensure system compliance and reliability. The Mars 12892 provides a compact, reliable solution for dual-motor HVAC systems, delivering consistent power for both start and run operations in demanding environments.
