MARS SPST NO Thermal Time Delay Relay (24V)

These time delay relays are used for a variety of applications in heating and air conditioning. They operate by means of a solid state PTC (positive temperature coefficient) device which heats up as current passes through it from the control circuit. This heat causes a positive, snap-acting disc to make or break the necessary contacts. Features: Shock & vibration resistant internal snap action automatic reset switch mechanism assures positive make/break action Non-positional Wide selection for any application Voltage and ambient compensated UL and CSA listed Used for electric heat, air conditioning, heat pumps, gas & oil furnaces, unit heaters and commercial refrigeration.
