More info
The mechanical thermostats KTO 111 are regulators for use up to 5,000 meters in altitude, thanks to optimised air gap and increased creep age distance. By use of Push-In terminals, the thermostat is wired tool-free. The Push-In terminals provide constant pressure on the wires to prevent them from coming loose (e.g. during transport).
KTO 111: Thermostat (NC); contact breaker for regulating heaters. The contact opens when temperature is rising.

1 Stripped length of rigid wire: 10 to 12 mm. When connecting with wires, wire end ferrules must be used (square or trapezoid crimp). Length of wire end ferrule: 10 mm or 12 mm.
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.
