Copeland 514-1246-00 Relay Assembly

The Copeland 514-1246-00 Capacitor and Relay Assembly is the factory start-assist package for single-phase Copeland compressors. Copeland catalogs it as a CAP & RELAY ASSM: a pre-wired capacitor and relay assembly housed in a galvanized steel enclosure with mounting flange feet and a color-coded wire harness (red, yellow, black and green leads) that exits through a rubber grommet. Everything the start circuit needs is sealed in one can, so the compressor gets its starting torque and the start components drop out of the circuit once the motor is up to speed. 514-1246-00 is part of the 514-1246-xx series, which also includes 514-1246-01, 514-1246-02 and 514-1246-03.

A single-phase compressor motor has little starting torque on its own. A start capacitor shifts current in the start winding to get the rotor turning, and a starting relay (a potential-type relay on most assemblies of this kind) opens the start circuit when the motor reaches speed. When these parts weaken, the compressor hums and trips on overload, starts slowly or not at all, short-cycles, or you find a bulging or leaking capacitor and burnt relay contacts. Replace the capacitor and relay together as an assembly so the two stay matched. Always shut off and lock out power and discharge the capacitor before touching the harness. Each 514-1246 dash number is its own assembly, so order the exact number on your original.

Key Benefits

• Complete Start Circuit: Capacitor and relay arrive pre-wired in one enclosure, so the pair stays matched and you skip separate component sourcing.
• OEM Copeland Assembly: Specified by Copeland as the 514-1246-00 start package, not a universal substitute.
• Rugged Steel Enclosure: The galvanized steel housing with mounting flanges protects the components and bolts down securely.
• Restores Reliable Starting: Cures hard starting, overload trips on start and short-cycling caused by a weak capacitor or worn relay.

Common Questions

• Is -00 interchangeable with -01, -02 or -03? Not automatically. 514-1246-00, 514-1246-01, 514-1246-02 and 514-1246-03 are separate Copeland part numbers; match the dash number on your original assembly.
• What symptoms point to this assembly? A compressor that hums but will not start, trips its overload on start, starts slowly, or short-cycles, along with a swollen capacitor or burnt relay contacts.
• Is there a safety step before replacement? Yes. Disconnect and lock out power and discharge the capacitor before handling the harness; a charged capacitor can deliver a hard shock.
