Lennox 45H03 DPDT Deltrol Relay 24V 275TM

The Lennox 45H03 Deltrol Relay is an electromechanical switch that is applied in different equipment of Lennox HVAC to manage electric current. It works like a switch which controls the circuits based on a control signal provided to it. This particular relay is a DPDT type which means that it can switch two circuits with just the help of one relay. It uses a normal 24V power supply and works with 50/60 Hz electrical supplies. They afford accurate control of heating and cooling, reduce safety risks by separating control circuits from high power circuits, and increase system reliability. Last, relays are also useful in the improvement of the system reliability since they form a reliable switching means.
