Copeland 514-1246-01 Relay Assembly

The Copeland 514-1246-01 Capacitor and Relay Assembly is a factory start-assist assembly for single-phase Copeland compressors, listed by Copeland as a CAP & RELAY ASSM. The capacitor(s) and starting relay come pre-wired inside a galvanized steel can with mounting flange feet and a color-coded lead harness (red, yellow, black and green) leaving through a rubber grommet, so you replace the whole start circuit in one step. 514-1246-01 sits in the 514-1246-xx series next to 514-1246-00, 514-1246-02 and 514-1246-03, and each of those is a separate, current part.

The job of the assembly is to give a single-phase compressor the starting torque it lacks on its own. The capacitor boosts current in the start winding, and the relay drops that circuit out once the compressor is running. A tired capacitor or pitted relay contacts cause slow starts, a compressor that hums and cycles on overload, repeated short-cycling, or a visibly swollen capacitor. Because capacitor and relay age together, replace them as a matched assembly rather than one at a time. Disconnect and lock out power first and discharge the capacitor before you touch any lead. Do not substitute a neighboring dash number unless your compressor parts list says so; 514-1246-01 should be ordered by the exact number on the original assembly.

Key Benefits

• One-Step Replacement: The pre-wired harness and enclosed capacitor and relay replace the entire start circuit at once.
• Specified by Copeland: Sold as Copeland 514-1246-01, the factory part, so ratings and relay characteristics match the original design.
• Durable Mounting: Galvanized steel enclosure with mounting flanges resists corrosion and bolts to the unit.
• Fixes Start Problems: Addresses hard starting, overload trips and short-cycling traced to a weak start capacitor or worn relay.

Common Questions

• Does -01 replace -00? No. 514-1246-01 and 514-1246-00 are both current, separate Copeland assemblies. Order the exact dash number that is on your original.
• What does the relay do? It connects the start capacitor while the compressor is coming up to speed and then opens that circuit so the capacitor is not left energized during normal running.
• How should I handle the capacitor? Lock out power, then discharge the capacitor safely before touching the harness. Capacitors can hold a dangerous charge after the unit is shut off.
