Thermal protectors series CH6/SH6

Application:

T hermal P rotectors (TP) of type H6 are specially designed to the requirements of middle-sized standard electric motors where a high short-circuit current appears and if after overheating and subsequent cooling an automatic resetting is required.

Design:

The temperature limiting switches H6 are based on the well proven mechanism of Thermik’s product series 06. Due to a reinforced contact system the SH6-protectors are adapted to higher currents. Versions : SH6 with insulation cap CH6 without insulation cap
Diameter d max. ( with / or without insulation cap ) 9.8 / 9.3 mm Height h max. ( with / or without insulation cap ) 7.6 / 7.2 mm Lengths of insulation cap

Operation:

l max. 17 mm If, in the case of overheating, the rated switching temperature of the bimetallic disc is reached, this suddenly snaps over and opens the contacts. After cooling down beyond its resetting temperature, the bimetallic disc resets to close the contacts.

Features:

High performance : maximal switching current 42 A Quick response sensitivity : featured by small protector mass and the brass - housing Excellent long term performance : due to instantaneous switching, fine- silver contacts, constant contact resistance and to electrically as well as mechanically unstressed bimetallic disc, reproducible switching temperature values Very short bouncing times :
