Heating & Cooling

SUPCO® offers the most complete line of refrigeration relays, overloads and hard starts in the industry. For refrigeration systems with and without run capacitors, just choose the right combination for your application. All combinations are pre-wired - Locked rotor protection eliminates start winding overheating - RO series features "snap-on" bracket - Can be used with and without start capacitor motors from 1/4 to 1/3 hp

Locked rotor protection eliminates start winding overheating - PRO series installs on "pin-type" terminal - Can be used with and without start capacitor motors from 1/4 to 1/3 hp

220 to 240VAC Solid-state Hardstart Relay, includes relay, overload, and start capacitor. Used on refrigeration systems with or without run capacitors. Rated for 1/12 HP to 1/5 HP compressors. Maximum RLA 1.66 Amps. - Prevents low voltage starting problems - Replaces relay, overload and provides a boost for hard start and unbalanced systems

Panel-Mount Controllers are compact and capable and provide excellent control options in a small package. These models are economical solutions for medium-temperature and low-temperature refrigerated cases, as well as standalone refrigerated display cases.

Split Controllers are designed to excel in more demanding applications and provide additional control options for more complex equipment. These controllers can be mounted to a wiring chase or with the refrigeration equipment, eliminating the need for long runs of control wiring. *Controller, cable and display must each be ordered separately
