Thermal protectors:
High temperature series


The switches are equipped with a high capacity contact mechanism, wherein the bimetal disc can move freely, without current flow through it.An additional spring disc maintains constant contact pressure until reaching its switching temperature.

normally closed (automatic resetting)::


Quick response sensitivity

featured by small protector mass and metal housing

Extraordinary stability

by using special high temperature materials

Instantaneous switching

with constant contact pressure over the whole temperature range

Excellent long term performance:

Reproducible switching temperature values due to instantaneous switching, fine silver contacts, constant contact resistance and electrically as well as mechanically unstressed bimetal disc
