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.
