Pfannenberg 17121000003 FLZ 530 – Enclosure Thermostat for Fans, -20 to +40 °C, N.O. Contact

The Pfannenberg 17121000003 is an FLZ 530 enclosure thermostat for controlling Filterfans® and cooling units. Its normally open (N.O.) contact closes when the cabinet temperature rises above the setpoint and opens again once the cabinet has cooled down.

This version has a low setting range of -20 to +40 °C. It suits applications where fans must start at a relatively low cabinet temperature, for example to protect sensitive electronics. It snaps onto a standard 35 mm DIN rail without tools.
