These devices maintain the pre-set temperature of the agent and — in case of failure of the regulator (thermostat) — the bimetallic limiter will automatically switch off the current in the controlled circuit as the pre-set temperature limit is reached, thus preventing overheating. Once the defection of the temperature regulation was repaired, in voltage-free state, the limiter can be re-started manually after the sensor has cooled down to room-temperature.
Working temperature range: 0 — 95 °C
Areas of application:
– electric water-heaters, boilers.
Trouble-free operation is conditioned by proper heat transfer between the sensor and the controlled medium.
