MICROTEMP thermal fuses from Therm-O-Disc

MICROTEMP® thermal fuses from Therm-O-Disc are available in a variety of standard and custom configurations, providing reliable one-shot over-temperature protection for a wide variety of applications. 
 
Z6 SERIES
Z6
Designed with a up to 380°C maximum temperature, the Z6 series MICROTEMP® thermal fuse can be utilized in applications where a higher maximum-overshoot temperature rating is needed, yet it is rated for operating currents up to 16 amps at 250VAC.
It is the same physical size as the G4, G5 and G8 series thermal fuses.
datasheet  
g4 SERIES

G4

Rated for continuous operating currents up to 10 amps at 250VAC (15 amps at 120VAC, 5 amps at 24VDC), the G4 series MICROTEMP® thermal fuse 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 also widely applied in office machines, portable heaters and industrial equipment as a thermal safeguard.
datasheet  
g5 SERIES

G5

Designed for higher voltage and current applications than the G4, the G5 series MICROTEMP® thermal fuse is rated for operating currents up to 20 amps at 250VAC and 277 VAC (25 amps at 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.
datasheet  
g6 SERIES

G6

The G6 series MICROTEMP® thermal fuse can be utilized in applications where a higher maximum-overshoot temperature rating is not required, yet it is rated for operating currents up to 16 amps at 250VAC.
It is the same physical size as the G4, G5 and G8 series thermal fuses.
datasheet  
g7 SERIES

G7

The G7 series MICROTEMP® thermal fuse is designed to satisfy applications requiring miniaturized components that do not need maximum current interrupt capability.
The G7 is just 2/3 the size of the G4 and G5, and with a current interrupting capability of 5 amps at 250VAC (5 amps at 24VDC), it can meet the requirements of transformers, motors, battery packs, clutch coils, and electronic circuit applications.
datasheet  
g8 SERIES

G8

Designed for very high–current applications such as major appliances and high-wattage electric heat packages, the G8 series MICROTEMP® thermal fuse is rated for operating currents up to 25 amps at 250VAC (20 amps at 277VAC).
More economical than electromechanical bimetal-type one shot devices, it can be utilized in applications where its small size is an advantage in terms of mounting (it is the same physical size as the G4, G5 and G6 series thermal fuses) and thermal response.
