Title: OVERVOLTAGE PROTECTION WITH INDICATION OF EXCEEDED OPERATING TEMPERATURE
Abstract:
An overvoltage protection with indication of exceeded operating temperature, where the overvoltage protection comprises at least one protection element from the group of a two-pole protection component (6), a two-pole protection component (6) complemented with a temperature dependent fuse (8), a three-pole protection component (7). All protection components used in the given overvoltage protection is linked via a thermal link (9) to the status indicator (10) consisting of a thermosensitive layer with irreversible change of colour in case a temperature of the destructed protection members of the overvoltage protection is exceeded.
