MARS 33242 Relay single-throw configuration provides a cleanThe MARS 33242 Relay is a specialized 24V SPST NO time delay relay engineered for precise control in HVACR systems. As a veteran grade HVAC compressor time delay solution, this component utilizes a solid state PTC (Positive Temperature Coefficient) device. When current flows through the control circuit, the PTC element heats an internal snap acting disc, facilitating a reliable make or break contact transition. This thermal time delay relay is
