Daikin-McQuay 106500101 Relay

The Daikin-McQuay 106500101 Relay is a heavy-duty DPST electric heat relay designed for precise load switching in high-amperage HVACR applications. Engineered with a 24V coil and rated for 30A resistive loads, this double-pole single-throw component is a direct replacement for failing sequences in older MicroTech and commercial air handling units. Its robust contact design handles the high inrush current typical of resistive heating elements, preventing premature pitting and contact welding. For technicians auditing system performance, this relay ensures reliable circuit isolation and thermal management. Whether you are performing a preventative maintenance swap or troubleshooting a Daikin-McQuay heater control circuit, this OEM-grade relay provides the exact electrical specifications required to maintain UL compliance and system safety. Integrating a high-quality HVAC power relay like the 106500101 minimizes voltage drops across the system, ensuring efficient power distribution to the heating banks even under continuous duty cycles.

• High Amperage Capacity: Rated for 30A, making it ideal for electric duct heaters and heavy-duty resistive loads.
• DPST Configuration: Provides simultaneous switching of two poles for complete circuit control and isolation.
• 24VAC Control Circuit: Compatible with standard Daikin-McQuay control systems and universal 24-volt transformers.
• OEM Compatibility: Precision-fit replacement HVAC relay designed to match original mounting footprints and terminal layouts.
• Durable Construction: Built to withstand the high temperatures found inside electrical control cabinets and blower compartments.

Is this relay compatible with non-Daikin HVAC units?
While designed for Daikin-McQuay heating systems, this relay can act as a universal replacement for any application requiring a 24V DPST switch rated for 30 amps.

What are the symptoms of a failing 106500101 relay?
Common indicators include heating elements staying energized (stuck closed) or failing to engage entirely (open coil or high resistance at contacts).

Can this relay handle inductive motor loads?
This component is primarily optimized for resistive heat loads; always verify the Full Load Amps (FLA) and Locked Rotor Amps (LRA) of your motor against the 30A resistive rating before installation.
