Q101 Supco Sequencer  C40-110 1 switch

The Supco Q101 1-Switch Electric Heat Sequencer is a heavy-duty, Single Pole Single Throw (SPST) sequential relay engineered to precisely manage heating elements and blower motors in electric forced-air systems. Featuring a 24V control circuit, this 1-time, 1-switch sequencer smoothly staggers system components to eliminate severe inrush current spikes and prevent your electrical panel from overloading.

With a standard thermal timing delay, the contacts are engineered to close within 1 to 40 seconds and open safely within 40 to 110 seconds, ensuring optimal residual heat distribution and steady airflow through your HVAC system.
