Pfannenberg 17105000003 FLZ 510 – Enclosure Thermostat, -20 to +40 °C, Changeover Contact, 1 K Switching Difference
The Pfannenberg 17105000003 is an FLZ 510 enclosure thermostat for precise temperature control in electrical cabinets. It has a changeover contact, so it can switch either a cabinet heater (N.C. side) or a Filterfan® / cooling unit (N.O. side).
This version combines a small switching temperature difference of about 1 K (230 V AC operation) with a low setting range of -20 to +40 °C. It suits cabinets in cold environments or outdoor installations that need tight frost and condensation control. It snaps onto a standard 35 mm DIN rail without tools.
