FZK 011 Mechanical Thermostat
- Wide adjustment range
- High switching capacity
- SPDT (change-over) contact
- Very low hysteresis option
- 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 loads via snap-action contact.
