¬ Note:When selecting a factory-installed control circuit transformer, use the transformer control coil voltage code to denote the transformer primary voltage. The transformer secondary voltage and starter coil will both be 120V AC by default. Example: Cat. No. 532-LAB-6P-24R will have a transformer with a 480V primary voltage, 120V secondary voltage, and a 120V starter coil voltage.
