About this item

Product details

●EXACT SPECS & SAFETY RATED: Premium 45+5 MFD dual-run capacitor rated for 370V/440VAC (50/60 Hz) in a standard round design. Built to rigorous UL safety standards with 10,000 AFC anti-explosion protection and safety switch integration (E332171 / C22.2 NO.190 AMB46C certified). ●UNIVERSAL HVAC COMPATIBILITY: Engineered to replace failed dual-run capacitors across top central AC and heat pump brands, including Carrier, Goodman, Trane, Bryant, Payne, Lennox, Rheem, and York. ●EASY DIY INSTALLATION: Features standard 1/4" quick-disconnect spade terminals clearly stamped for fast wire identification (C for Common, HERM for Compressor, FAN for Fan Motor) to get your cooling system running in minutes. ●HEAVY-DUTY CBB65 CONSTRUCTION: Built with self-healing metallized CBB65 polypropylene film, non-PCB synthetic plant oil, and surge-resistant construction rated for operating temperatures from -40°C to +70°C to handle severe summer heat waves. ●RELIABLE QUALITY & SUPPORT: Factory-tested to strict OEM specifications to ensure long-term durability, backed by CoralVolt product support for hassle-free replacements and peak summer cooling confidence. HOW TO MATCH YOUR OLD CAPACITOR: Read the label on your old capacitor and match it: (1) the same µF (MFD) rating, for example 45+5; (2) a voltage rating of 370V or 440V (a 440V capacitor can replace a 370V one, but not the other way around); (3) the same shape, round or oval, so it fits the mounting bracket. Connect wires to the matching terminals: HERM to the compressor, FAN to the outdoor fan motor, C to common. Take a photo of the wiring before removing the old part. Turn off power and discharge the old capacitor before installing.
  • CORALVOLT 45+5 uF ±6% 370/440 VAC CBB65 dual run start capacitor replacement for BOTH 370 & 440 Volt capacitors.
  • 45/5 MFD Capacitor size measures ( 1.97inch / 50mm ) in Diameter x ( 3.35inch / 85mm ) in Height.
  • Operating temperature: -40℃ to +70℃/-104℉ to +158℉. Frequency: 50/60 Hz. Safety rated: 10,000 AFC - Available Fault Current.
  • SUPER EASY to Replace: Direct replacement, No wiring or adapter changes required. AC Capacitor has three terminals on the top are labeled "Herm" for the compressor motor, "Fan" for the fan, and "C" for the common line.
