Purchase now: Pfannenberg 17099910030 FLZ 510 Thermostat
Purchase now: Atlantech Drives provides you the Pfannenberg 17099910030 (Model: FLZ 510), the industry-standard NC (Normally Closed) Thermostat designed for the precise control of enclosure heaters. In industrial environments where temperature fluctuations can lead to hazardous condensation, the FLZ 510 serves as the «brain» of your thermal management system. By detecting when the internal temperature drops below a set threshold, it activates the heater to raise the temperature above the dew point, preventing corrosion on sensitive busbars and electronics.
Technical Specifications and NC Logic
The FLZ 510 features a distinct Red Dial to signify its function for heating control. It utilizes a bimetallic sensor element that ensures reliable switching behavior with a hysteresis of approximately 7 Kelvin. The NC Contact opens when the temperature rises, turning the heater off to save energy. It handles switching loads up to 240 V AC / 10 A, making it capable of directly driving most standard fan heaters without an intermediate contactor.

Expert Installation Advice: Positioning is Key
The placement of the thermostat dramatically affects its accuracy. Expert Tip: Always mount the FLZ 510 in the upper part of the cabinet, as far away as possible from the heater itself. If you mount it right next to the heater, it will detect the hot air plume and shut off prematurely (short-cycling), leaving the rest of the cabinet cold and vulnerable to condensation. Ensure it is also away from direct airflow of cooling fans.
Frequently Asked Questions (FAQs)
Q: Can I use this to control a cooling fan?
A: No. The FLZ 510 has an NC contact (opens on temperature rise). For cooling fans, you need the FLZ 520 (Blue Dial, NO contact) which closes on temperature rise.
Q: Is it suitable for DC voltage?
A: Yes, it can switch DC loads (max ~30W typically), but always verify the DC switching curve to prevent contact welding.
