FZK 011
Winston
Features
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, fil-
ter 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.
