TE Connectivity KUHP-5A51-120 Relay

The TE Connectivity KUHP-5A51-120 is a high-capacity, general-purpose 30 Amp power relay designed for demanding HVACR and industrial control applications. This SPDT (1 Form C) relay features a 120VAC coil and is engineered for panel mounting with a rugged bracket mount case. Its construction includes dual-pin quick-connect terminals that also support solder connections, ensuring a secure interface in high-vibration environments. Designed to handle high-inrush currents, the KUHP-5A51-120 is a reliable solution for switching compressors, motors, and heating elements. The enclosed clear plastic dust cover protects the silver cadmium oxide contacts from environmental contaminants, maintaining low contact resistance across heavy-duty electrical loads. This panel plug-in relay serves as a direct replacement in many legacy control panels where faston terminal 120V relays are specified for high-amperage switching.

• High Amperage Capacity: Rated for 30A at 240VAC, meeting the requirements for heavy-duty motor and heater circuits.
• Versatile Mounting: Integrated bracket mount case allows for secure installation directly to panels or enclosures.
• Reliable Termination: .250-inch quick-connect terminals facilitate rapid wiring while providing the option for permanent solder joints.
• Environmental Protection: Enclosed housing prevents dust and debris from fouling the internal contact mechanism.
• Standardized Footprint: The KUHP series architecture ensures compatibility with existing high-power relay configurations in commercial HVAC systems.

What is the maximum contact rating for this relay?
This unit is rated for 30 Amps at 240VAC and 1 HP at 120VAC, making it suitable for both resistive and inductive industrial loads.

Can this relay be used with a standard plug-in socket?
While the KUHP-5A51-120 has plug-in capabilities, it is specifically designed with a bracket for surface mounting to handle the mechanical stresses of high-current switching.

What are the coil specifications?
The coil is designed for 120VAC 50/60Hz operation with a nominal power consumption of approximately 2.9VA.
