Resistance Temperature Detector
Provide stable output from wide range
of temperature
Re-adjustable while checking its
precision
Steady for a long time
More linear characteristic than thermo

If highly sensitive, instruct precise
temperature within small temperature
ranges.
TRIO Unit can measure temperatures among ACB’s terminals, and detect its degree of loads from the heat.
In this equipment, it is possible to measure breaker’s terminal temperature by using thermistor and RTD.
Ambient temperature subtracted from temperature measured is the Temperature-rise Limit.
Temperature-rise Limit for external connecting terminal is bound to 80° by the standard.
From TRIO Unit, it will send a warning message at 80° to user through its alarm.

The measured value by a temperature sensor
becomes a sampling through MCU’s internal
ADC, and exchange information with upstream
through 485 communication line.
