Product Name：Mechnical Thermostat FZK 021
Product Model：FZK 021
¹ If the Normally Closed contact is used, the switch temperature difference could be reduced by connecting terminal
"N" (RF heating resistor).It causes the thermal feedback which is subject to surrounding conditions and thus has to be determined for each individual application.
² When connecting with wires, wire end ferrules must be used.
> Adjustable temperature
> High switching capacity
> Small hysteresis
> Change-over contact
> Clip fixing
The mechanical thermostat is used for controlling heating and cooling equipment, filter fans or signal devices. The thermostat registers the surrounding air and can switch both inductive and resistive loads via snap-action contact.
Functionality: The temperature setting on the scale equals to the upper switch point, which means that the NC contact opens. The temperature setting minus switch temperature difference (and tolerances) equals to the lower switch point,which means that the NC contact closes.
