Prestazioni di commutazione elevate
NT 37-F / NT 37-M: Thermostat (normally closed); interruttore di contatto per la regolazione dei riscaldatori. Il contatto si apre quando la temperatura aumenta.
NT 38-F / NT 38-M: Thermostat (normally open); contattore per la regolazione di ventilatori con filtro e scambiatori di calore o per la commutazione di segnali quando viene superato il limite di temperatura. Il contatto si chiude quando la temperatura aumenta.
