Supco SUPR Potential Relay

The Supco SUPR 30A Universal Potential Relay is a reliable, field-proven solution for technicians requiring a versatile wire-to-wire replacement for virtually any potential relay in the HVACR industry. Built with advanced Electronic Potential Relay (EPR) technology, this unit is designed to handle single-phase motors and compressors up to 5 HP. This model is the direct replacement for 76C35, ensuring seamless HVAC compressor motor starting across a wide operating voltage range of 110V to 270V AC. Its non-positional mounting capability allows for installation in any orientation, a critical advantage in tight service cabinets where traditional mechanical relays might fail due to gravity sensitivity.

Engineered for high-performance motor start assist, the SUPR includes a safety time-out feature of 1.0 to 1.5 seconds to provide start winding protection if the motor fails to turn over. The normally closed 30 Amp contacts and instant restart capability ensure the system is ready for the next cycle without the cooling delays associated with standard thermal components. Whether you are performing a potential relay troubleshooting repair or a proactive system upgrade, the included universal mounting bracket and screw-on terminals (with push-on adapters) make this the versatile choice for residential and commercial air conditioning parts sets.

• Universal Compatibility: Functions as a universal wire-to-wire replacement for old 3 and 5 terminal potential relays, including the 76C35.
• EPR Technology: Utilizes electronic sensing for precise motor starting, eliminating the points-sticking issues found in mechanical potential relays.
• High Capacity: Rated for motors up to 5 HP with heavy-duty 30A universal potential relay contacts.
• Flexible Installation: Non-positional design and snap-off bracket mounting allow for use in any physical orientation or space constraint.
• Integrated Protection: Features a built-in time-function relay for safety shutdown and rapid system recovery.

• Can this relay replace a specific OEM potential relay? Yes, the SUPR is designed to replace almost any 3-terminal or 5-terminal potential relay regardless of the brand or orientation.
• Is this compatible with both 115V and 230V systems? It is rated for a wide voltage range (110 VAC to 270 VAC), making it suitable for both 115V and 230V single-phase applications.
• Does the mounting orientation matter for the SUPR? No, unlike mechanical relays that must be mounted perfectly upright, this electronic relay functions accurately in any position.
