Reznor 263530 Relay

The Reznor 263530 is a heavy-duty 120V coil relay engineered for reliable switching in commercial and industrial HVACR systems. As a direct Reznor replacement part for legacy models 103318 and 103319, this component ensures seamless integration into existing control circuits without requiring field modifications. In high-demand environments, this relay manages the interface between line-voltage equipment and control systems, providing the high-torque switching capability necessary for unit heater fans and automated machinery. Also referenced by the manufacturer as 9400-04T180, this 120-volt heating relay features a compact footprint, making it ideal for tight electrical cabinets where space is at a premium. For technicians servicing Reznor unit heaters, utilizing an OEM Reznor relay is critical for maintaining circuit integrity and equipment performance standards. This electronic component is built to withstand the cycling demands of industrial air heaters, ensuring consistent electrical contact and reducing the risk of control circuit failure during peak heating loads.

• OEM Compatibility: Serves as the official replacement for Reznor 103318 and 103319, ensuring precise fit and function.
• 120V Control: Optimized for standard 120-volt circuits commonly found in industrial HVAC and automation applications.
• Durable Construction: Built to professional standards to handle repeated switching cycles in demanding mechanical environments.
• Compact Design: Small form factor allows for easy installation in crowded control panels and equipment housings.

How do I know if my Reznor relay needs replacement?
If you hear repeated clicking from the control cabinet without the fan or burner engaging, or if your unit heater fails to start despite receiving a thermostat signal, the Reznor 263530 may have failed open or experienced coil burnout.

Can I use the 263530 to replace the older 103318 or 103319 models?
Yes, the Reznor 263530 is the direct manufacturer-specified replacement relay for both the 103318 and 103319 part numbers, engineered to meet the same electrical specifications.

What is the primary function of a 120V coil relay in a unit heater?
This relay operates as a switch, using a 120V signal to open or close contacts that power high-voltage components like blower motors, ensuring the control logic can safely manage high-current draws.
