Rate-of-rise thermal detector TM 3-D

This detector combines the response characteristics of our fixed temperature thermal detectors TM 2-M and TM 3-M as well as our rate-of-rise thermal detector TM 2-D.

The rate-of-rise/fixed temperature thermal detector reacts when a temperature of approx. 58 °C is exceeded or when the temperature rises by 8 °C/min. Alarms are indicated by a red LED.

Thanks to its quarter-turn fastener, it can be easily mounted on a standard or relay base. The detector is also secured against sabotage and removal.
