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.

Switch temperature difference 7 K (±4 K tolerance)
Sensor element thermostatic bimetal
Contact type snap-action contact
Service life 100,000 cycles verified
Max. operating voltage, frequency range AC 250 V, 50-60 Hz
Max. inrush current AC 16 A for 10 sec.
Connection1 2 Push-In clamps
rigid wire 2.5 mm² (AWG 14)
stranded wire1 1.5 mm² (AWG 16)
Mounting clip for 35 mm DIN rail, EN 60715
Casing plastic according to UL94 V-0, light grey
Dimensions 60 x 33 x 41 mm
Weight approx. 40 g
Fitting position variable
Operating/Storage temperature -45 to +80 °C (-49 to +176 °F)
Operating/Storage humidity max. 90 % RH (non-condensing)
Protection type/Protection class IP20 / II
Overvoltage category/Altitude II: up to 5,000 m; III: up to 2,000 m

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.
