Electric Heat Sequencer Relay 240V Therm O Disc 12S22

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
