FZK011 MECHANICAL THERMOSTAT
- High switching capacity
- Small hysteresis
- Terminals easily accessible
- Adjustable temperature
- Change-over contact
- Clip fixing
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.

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 stranded wires, wire end ferrules must be used.
3 Voltage only needs to be specified if the optional use of the RF resistor is desired.
Important note: The contact system of the regulator is subjected to environmental influences, thus the contact resistance may change. This can lead to a voltage drop and/or self-heating of the contacts.
