meet application requirements (see figure 3). There are five primary types of thermal cutoffs

available. Standard dimensions of each TCO series are shown in figure 4.

G4 Series

Rated for continuous operating currents up to 10 amps @ 250VAC (15 amps @ 120VAC), the G4

series MICROTEMP

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.

G5 Series

Designed for higher current applications, the G5 series MICROTEMP

currents up to 16 amps @ 250VAC (20 amps @ 250VAC and 25 amps @ 120VAC at UL/CSA).

Similar in appearance to the G4 series, the G5 series has a different internal construction designed

for interrupting higher currents.

G6 Series

The G6 series MICROTEMP

temperature rating is not required, yet it is rated for operating currents up to 16 amps @ 250VAC.

It is the same physical size as the G4, G5 and G8 series TCOs.

G7 Series

The G7 series MICROTEMP

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 @ 250VAC, it is capable of meeting the

requirements of transformers, motors, battery packs and electronic circuit applications.

G8 Series

Designed for very high-current applications such as major appliances and high-wattage electric

heat packages, the G8 series MICROTEMP

250VAC. 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’s the same

physical size as the G4, G5 and G6 series TCOs) and thermal response.
