Overtemperature Indicators

Temperature-responsive color changes as apassive visual alert system for hazard detection
and prevention.

The Thermo Clip™ Series serves as reliable
overtemperature indicators for electrical assets,offering a visual means to monitor temperature
variations and potential issues within electricalsystems.

Memory-Effect Feature

Patented Thermochromic Technology

These non-conducive clips possess amemory-effect feature, enabling inspectors toview a permanent record of overtemperature
excursions in intermittently loaded systems.
This feature aids in tracking and analyzing
temperature trends over time, contributing toasset health and safety monitoring.

These clips feature patented Thermochromictechnology, allowing them to change color as a
response to temperature changes.
This technology ensures a clear and permanentvisual indicator of overtemperature conditions.

36kVAC/600VDC*Installation: ThermoClipTM Series Clips are designed to be push fitted only onto the outer insulation of a cable, adjacent (15mm-30mm distance) to its
connection terminal. ThermoClipTM should not be inserted anywhere into the current carrying path of the circuit or directly attached to bare live metalparts of the circuit.
*Caution: ThermoClipTM Series are designed for use on electrical cables and as such installation must be assessed by a competent electrician licensed
to applicable local requirements prior to their application.
