Keeping heat pumps operating at peak efficiency ensures the comfort of building occupants and saves money. Consult this block diagram to identify


The HCC Series Definite Purpose Contactors consists of 1 pole, 2 pole, 3 pole, and 4 pole contactors from 20 amperes through 40 amperes (1P, 2P, and 4P) and 20 amperes through 60 amperes (3P). Acting as an on/off switch controlled by thermostats, contactors are designed with consistent silver thickness for increased product life, making them ideal for the demands of a broad range of applications. The 1 and 2 pole models are typically used in residential applications, while the 3 pole contactors are typically used in commercial applications. Meets NEMA standards and complies with the A2L refrigerant requirement of UL Category Control Number (CCN) LZGH2/8 for Annex JJ of UL 60335-2-40.
