Overheating of the Bus-bar can reduce the life of the
insulation sleeves, Bus-bar / cables & even Breakers. Periodic
loading conditions can cause the metal to heat and cool
continuously resulting in the deterioration of the Bus-bar
material and loosening of the joints. This becomes even
more critical in case if Bus-bars consist of metals of different
heat coefficient.

Pick up (Tp) - 85 C to 115 C
ii. Pre alarm - 0.5Tp to 0.95Tp in the steps of 0.05Tp
iii. Delay - 0 Min to 15 Mins in Steps of 1 Min (It delays the tripping of the breaker by the set delay time.)
iv. Input supply - 24V DC (Directly at Module Terminals)
Temperature Module senses the real time temperature at the Cradle terminals and displays on the Matrix release
screen. TM module can be used to give alarm on the release or to trip the breaker with the temperature pickup
