Ensure your HVAC system or electrical appliance operates with precision and safety using this high-quality 24-volt sequencing relay. Designed as a Single Pole Single Throw (SPST) electrical switch, this component is essential for managing high-current loads up to 16 Amps. As a normally open relay, it provides reliable circuit control by remaining open until energized by a low-voltage signal, making it a critical part for staging heating elements, blower motors, and other high-demand components in furnaces, heat pumps, and air handling units. Replacing a faulty relay can restore proper timing to your system, prevent electrical malfunctions, and improve overall energy efficiency.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
