Mechanical Thermostat FZK 011

Mechanical Thermostat FZK 011 Available in F or C scale Change-over contact High switching capacity DIN rail mountable

Mechanical Thermostat FZK 011

Wide adjustment rangeAvailable in °F or °C scaleChange-over contactHigh switching capacityDIN rail mountableThe FZK 011 Thermostat is designed to control the air temperature inside of enclosures and control panels.  It can be used for enclosure heaters, cooling equipment (e.g. filter fans), or signal devices.An integrated resistor (RF) can be connected to increase accuracy when the FZK 011 is used with an enclosure heater1).
