TE Connectivity KUP-5A15-120 Relay

The TE Connectivity Potter & Brumfield KUP-5A15-120 is a heavy-duty general purpose panel plug-in relay engineered for reliable 120V AC coil operation in industrial HVACR and automation control circuits. Featuring a Single Pole Double Throw (SPDT / 1 Form C) contact configuration, this 10A power relay utilizes silver cadmium oxide (AgCdO) contacts to ensure long-term durability under demanding switching loads. The unit is housed in a rugged enclosed socket mount case, providing protection against environmental contaminants while allowing for versatile installation via quick-connect terminals or solder connections. Whether you are replacing a faulty KUP-5A15-120 relay in an existing control panel or designing a new HVAC 120VAC control circuit, this component delivers consistent switching performance with minimal mechanical wear. The standardized pin layout ensures seamless integration into standard 8-pin or compatible sockets, making it a staple for contractors requiring a dependable 120-volt plug-in relay for inductive and resistive motor loads.

Technical Benefits

• High Contact Rating: Supports 10 Amps at 240VAC/28VDC, ideal for pilot duty and motor control applications.
• Versatile Termination: Features dual 0.187" (4.75mm) quick-connect/solder terminals for flexible wiring options.
• Integrated Protection: The transparent polycarbonate dust cover ensures internal components remain clear of debris.
• Compact Footprint: Designed for high-density panel mounting without compromising thermal dissipation.

Common Technical Questions

What is the coil resistance and voltage for this model?
The KUP-5A15-120 operates on a 120VAC coil with a nominal resistance of approximately 2,250 Ohms, drawing roughly 2.0VA to 2.7VA during operation.

Can this relay handle high-inrush motor loads?
Yes, the AgCdO contacts are specifically designed to handle the inrush current associated with 1/3 HP motors at 120VAC, preventing contact welding.

Is this a direct replacement for other KUP series relays?
This is an SPDT variant; verify your circuit requirements if replacing a DPDT or 3PDT unit. It fits standard KUP-style 11-pin or 8-pin sockets depending on the terminal footprint.
