Pfannenberg FLZ 520 NC Thermostat, 10A, 250 V, 20 → 80 °C

The Pfannenberg Thermostats are used as temperature regulators and thus to control filterfans, electrical cabinet heaters or can serve as an alarm setpoint. They are available as N.C. / N.O. and changeover contacts. In combination with electrical cabinet heaters, they can control temperature and also, particularly in outdoor applications, ensure that the electrical cabinet is 'artificially' dehumidified. This means that the temperature is kept over the dew point so that no condensation forms from the air preventing a potential short circuit. The combination with filterfans provides additional savings on energy, maintenance time and therefore provides a better environmental balance which improves the filterfans effectiveness. The twin thermostat series combines two thermostats in all combinations for complex switching tasks.
