THERMODISC THERMAL FUSES 

Phone:1-847-985-8383

Advance Technical Components, Inc. is a leading distributor for Thermodisc G4,G5,G7 series Thermal Cutoffs.

MICROTEMP® thermal fuses offer an accurate, reliable solution to the need for upper limit temperature protection against overheating by interrupting an electrical circuit when operating temperatures exceed the rated temperature of the thermal fuse.

·        Features and Benefits:

·        One Shot operation cuts off electrical current

·        High current interrupt capacity for applications requiring up to16amps@ 250VAC  (25amps120VAC)

·        Low Resistance

·        Compact size facilitates mounting in confined spaces

·                 Upper Limit Temperature Protection

·        MICROTEMP®, the original thermal fuse from Therm-O-Disc, offers the broadest combination of globally certified temperatures and electrical loads, as well as the broadest range of packages, mountings and design configurations on the market today.

·                 MICROTEMP Features:

·        Globally certified temperatures and electrical loads

·        One-shot operation cuts off electrical power

·        Current interruption capacity up to 25 amps @ 250VAC

·        Low resistance

·        Compact size

·        RoHS compliant

·                 Operating Principle

The active trigger mechanism of the thermal fuse is an exclusively formulated, electrically nonconductive pellet. Under normal operating temperatures, the solid pellet holds spring loaded contacts closed. When a predetermined temperature is reached, the pellet melts, allowing the compression spring to relax. The trip spring then slides the contact away from the lead and the circuit is opened. After the thermal fuse opens a circuit, the fuse needs to be replaced. This replacement procedure must include correction of the fault condition before the product is operated again.
