Connection 2-pole terminal, clamping torque 0.5 Nm max.: 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 43 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 IP20 ¹ When connecting with wires, wire end ferrules must be used. 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. The mechanical thermostats KTO 011 and KTS 011 are two state regulators used to control heaters, coolers, filter fans or signal devices. KTO 011: Thermostat (NC); contact breaker for regulating heaters. The contact opens when tempe rature is rising. KTS 011: Thermostat (NO); contact maker for regulating of filter fans and heat exchangers or for swit ching signal devises when temperature limit has been exceeded. The contact closes when temperature is rising. > Large setting range > Small size > Simple to mount > High switching performance Connection diagrams Thermostat KTO 011 (NC) Thermostat KTS 011 (NO) Examples of connection e.g. Signal deviceThermostat KTS 011 (NO) e.g. FanThermostat KTS 011 (NO) HeaterThermostat KTO 011 (NC) Heater Filter fan, Cooling equipment, Signal device SMALL COMPACT THERMOSTAT KTO 011 / KTS 011 REGULATING Setting range Art.
