CSR-U1 Compressor Saver Relay and Start Capacitor

The 5-2-1 Compressor Saver CSRU1 is used in 1-to-3 tons for scroll/reciprocating applications. A 5-2-1 COMPRESSOR SAVER significantly reduces the amount of time your compressor is on high amp start-up. Some top-of-the-line A/C units come from the factory with 5-2-1 technology built in. Now you can have a 5-2-1 COMPRESSOR SAVER installed in your A/C unit by a professional. The 5-2-1 COMPRESSOR SAVER uses a powerful multi-layer starting capacitor and a smart switch to give your compressor the boost it needs to start up quickly, more reliably, draw less power and save you money, too.
