Ranco T34-131 Delay/Sequence 30067439-890 any current detected above thisAs a field tested technician, you know that protectve controls are the frontline defense for any compressor. The Ranco T34 131 is a 208 240V HVAC time delay relay specifically engineered to eliminate compressor short cycling and prevent premature equipment failure during power flickers or pressure cut outs. This sequence control manages the critical rest period between cycles, ensuring that head pressures equalize before the motor attempts to restart
