MICROTEMP G5A01121C Cross UL VDE CCC One-shot Thermal Fuse 16A 250V 121C Cutoff

Description Of The One-shot Thermal Fuse 16A 250V 121C Cutoff

The G5 MICROTEMP series cross from Ampfort are compact size, global standard thermal cut-offs. AMPFORT thermal fuses offer an accurate, reliable solution for upper limit temperature protection against overheating. These thermal cut-offs interrupt an electrical circuit when operating temperatures exceed rated temperature of thermal fuse. The BFX series thermal cut-offs are designed for higher voltage and current applications. The global agency recognition of the BFX series enables use in a wide range of applications including major appliances and HVAC. These series has a different internal construction designed for interrupting higher currents and withstand higher temperatures.

Upper Limit Temperature Protection Of The One-shot Thermal Fuse 16A 250V 121C Cutoff

Ampfort thermal cutoffs offer an accurate, reliable solution to the need for upper limit temperature protection. Known as a thermal fuse, thermal link, or TCO, the thermal cutoff provides protection against overheating by interrupting an electrical circuit when operating temperatures exceed the rated temperature of the cutoff.

Operating Principle of the TCO Of The One-shot Thermal Fuse 16A 250V 121C Cutoff

The active trigger mechanism of the thermal cutoff 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 (see figures 1 and 2). After a thermal cutoff opens a circuit, the TCO needs to be replaced. This replacement procedure must include correction of the fault condition before the product is operated again.
