Supco Q103 Sequencer 1 time 2 switch

The Supco Q103 2-Switch Electric Heat Sequencer is a field-proven, heavy-duty sequential relay engineered to precisely control heating elements and blower motors in electric, gas, or oil forced-air systems. Designed with a 24V control circuit, this 1-time, 2-switch sequencer staggers the activation of components to eliminate severe inrush current spikes and safeguard your electrical panel against overloads.

Equipped with a built-in 5-second delay between subsequent stages, it ensures your system ramps up smoothly. Contacts M1-M2 are engineered to activate first and deactivate last, optimizing thermal efficiency and maintaining steady airflow across your heat exchangers or elements.

• Optimized Timing: Turns on within 1 to 20 seconds and turns off within 40 to 110 seconds.

• Broad Compatibility: Safety-certified direct replacement for a massive array of OEM parts, including popular White-Rodgers, Carrier, and Coleman models.
