    Thermal Fuse Technical Info


    Upper limit temperature protection.


    MICROTEMP thermal cutoffs from Thermo-Disc offer an accurate, reliable solution to the need for upper limit temperature protection.  Known as a thermal fuse, thermal link or TCO, the MICROTEMP thermal cut off provides protection against overheating by interrupting the electrical circuit when operating temperatures exceed the rates temperature of the cutoff.


    MICROTEMP features:

    One shot operation cuts off electrical power

    Current interrupt capacity up to 25amp @250VAC     42421937.jpg

    Low resistance

    Compact size


    G4 Series

    Rated for continuous operating currents up to 10 amps @250VAC (15amps @ 120 VAC, 5amps @ 24VDC), the G4 series MICROTEMP TCO is the industry standard for over-temperature protection. The G4 series is applied to millions of appliances and personal care products each year, providing reliable back up protection for temperature controlling thermostats and other over-temperature conditions.  The G4 series is widely applied in office machines, portable heaters and industrial equipment as a thermal safeguard.


    G5 Series

    Designed for higher voltage and current applications than the G4, the G5 series MICROTEMP TCO is rated for operating currents up to  20 amps @ 250VAC and 277VAC (25 amps @ 120VAC). Similar in appearance to the G4 series, the G5 series has a different internal construction designed for interrupting higher currents and withstanding higher temperatures.


    G7 Series

    The G7 series MICROTEMP TCO is designed to satisfy applications requiring miniaturized components that do not need maximum current interrupt capacity.  The G7 is just 2/3 the size of the G4 and G5, and with a current interrupting capability of 5amps @ 250VAC (5amps @24VDC), it is capable of meeting the requirements of transformers, motors, battery packs and electronic circuit applications.
