Pfannenberg 17111000000 FLZ 520 – Enclosure Thermostat for Heaters, 0–60 °C, N.C. Contact
The Pfannenberg 17111000000 is an FLZ 520 enclosure thermostat that controls cabinet heaters. Its normally closed (N.C.) contact opens when the cabinet temperature rises above the setpoint and closes again when it falls. This keeps the heater running only when it is needed, which helps prevent condensation and frost inside the enclosure.
You set the temperature from 0 to 60 °C on a dial. The unit snaps onto a standard 35 mm DIN rail without tools, and it is UL Recognized for easy integration into UL 508A panels.
