These safety devices automatically switch off the current in the controlled circuit as the temperature is reached, and switch it on again as the temperature falls below the set threshold value. The temperature of the controlled medium is thus maintained within a narrow zone. The limiter makes a last full annexation in case of mechanics injury.
Working temperature range: 77 – 350 °C
Areas of application:
– boilers for central heating
– water heater
– saunas and where a manual-reset safety device is required.
Trouble-free operation is conditioned by proper heat transfer between the controller’s sensor and the controlled medium.
In case of capillary-damage or lquid-leakage, the device will cut the circuit one last time as positive safety-feature.
