Pfannenberg 17111000004 FLZ 520 – Enclosure Thermostat, +20 to +80 °C, N.C. Contact
The Pfannenberg 17111000004 is an FLZ 520 enclosure thermostat with a normally closed (N.C.) contact. The contact opens when the cabinet temperature rises above the setpoint and closes again when it falls. This makes it suitable for controlling cabinet heaters, or for switching off a load when the cabinet gets too hot.
This version has a high setting range of +20 to +80 °C for applications where the switching point must sit at elevated temperatures. It snaps onto a standard 35 mm DIN rail without tools.
