High Current Thermal Fuse

The HCTF series is especially designed for high current

applications with an operation temperature up to 160 °C.

In case of excess heat in the range of the functioning

temperature of (235 ± 15) °C the thermo fuse opens

automatically

and

disconnects

the

circuit.

Typical

applications are automotive power electronics that are

connected to steady battery power (B+ or terminal

number 30).
