Description
The Trane BAYKSKT250A is a factory-engineered hard start kit designed to deliver a powerful boost of starting torque to single-phase compressors, reducing the time the compressor spends in its high-amperage startup phase. Rated at 112 MFD and 330 volts, this kit is a direct OEM replacement for compatible Trane and American Standard systems, ensuring a precise fit and reliable performance.
Why Use a Hard Start Kit?
Compressors are among the most electrically demanding components in any HVAC system. During startup, they draw several times their normal running amperage. A hard start kit adds a start capacitor and relay to the compressor circuit, dramatically shortening the startup cycle. This reduces heat buildup in motor windings, lowers stress on contactors and wiring, and can extend compressor service life — particularly in systems that experience low-voltage conditions, long refrigerant line sets, or frequent short-cycling.
