FIELD: physics.
SUBSTANCE: air circuit breaker with a temperature sensor comprises: a partition in form of an arm for dividing the inner space of the moulded base under each electric supply phase, a temperature sensor which detects temperature owing to that it is immovably inserted into an opening for inserting the sensor oon the said partition, and a temperature indicator which shows the value detected by the temperature sensor as temperature of the electroconductive unit, through which temperature inside the circuit breaker can be monitored.
EFFECT: avoiding damage caused by overheating of the electroconductive unit.
