Why is the machine heated at 25 A?
Hello, I need help. In the garage there are two Noirot electric convectors of 2 kW each, a circuit breaker of 25 Amps is heated. What could be the reason? The wire contacts are all extended, the machine put a new one, it did not help.

Hello! How hot is it? In general, as if the machine could be warm, this is due to its design, because a thermal release is installed in the mechanism, due to which the contacts are disconnected. We wrote more about this in the article - https://our.electricianexp.com/en/naznachenie-i-xarakteristika-avtomaticheskix-vyklyuchatelej.html If the machines are very hot, maybe they are defective or of dubious quality, what kind of manufacturer? Another reason for heating circuit breakers is poor ventilation in the panel, as well as the thermal effects of neighboring devices installed in the panel. I would also like to note that aluminum itself is prone to heat (if the wiring is aluminum). Well, the last tip - you can try separately for each convector to install an automatic machine with a nominal value of 16 Amps and see how the devices will behave with this connection scheme.
