FZK011 Thermostat

RM225.81




  1. Wide adjustment range
  2. High switching capacity
  3. SPDT (change-over) contact
  4. Very low hysteresis option
  5. DIN rail mountable



The FZK 011 mechanical thermostat is used for controlling heating and cooling equipment, filter fans or signal devices where a higher degree of sensing accuracy is required. An integrated resistor (RF) can be connected to improve the switch temperature difference (see Option note).

The thermostat registers the surrounding air and can switch both inductive and resistive loadsvia snapaction contact.
