KTO-111-KTS-111
1Pages

The mechanical thermostats KTO 111 and KTS 111 are two state regulators for use up to 5,000 meters in altitude, thanks to optimized air gap and increased creepage 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. KTS 111: Thermostat (NO); contact maker for regulating of filter fans and heat exchangers or for switching signal devises when temperature limit has been exceeded. The contact closes when temperature is rising. • Safe wiring with Push-In connection terminal • Faster and tool-free wiring • Improved air intakes for ventilation • Easy adjustability of switch temperature setting • For use in up to 16,000 ft. altitude Technical Data Sensor element thermostatic bimetal Contact type snap-action contact 100,000 cycles verified Max. operating voltage, frequency range 2 Push-In clamps rigid wire 2.5 mm² (AWG 14) stranded wire 1.5 mm² (AWG 16) plastic according to UL94 V-0, light grey Fitting position Operating/Storage temperature Operating/Storage humidity Protection type/Protection class Thermostat KTO 111 (NC) Service life Dimentioned Drawing Switch temperature difference Overvoltage category/Altitude II: up to 5,000 m; III: up to 2,000 m ¹Stripped 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.
