Wide adjustment range

High switching capacity

SPDT (Change-over) contact

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.

1)

The thermostat registers the surrounding air and can switch both inductive and resistive loads
via snap-action contact.

Switching difference approx. 7°F (4K), ± 2.7°F (1.5K) tolerance
