These devices automatically switch off the current in the controlled circuit as the pre-set temperature limit is reached, thus preventing overheating. Once the problem related to temperature regulation is resolved, in voltage-free state, the limiter / protective guard can be re-started manually.
Working temperature range: 0 – 355 °C
Areas of application:
– heat-storing stoves
– large hot water storage tanks
Trouble-free operation is conditioned by proper heat transfer between the protective limiter’s sensor and the controlled medium.
