STEGO KTO 111 and KTS 111 series compact thermostats

STEGO’s KTO 111 and KTS 111 series thermostats are set to replace the KTO 011 and KTS 011 series products. They are familiar to installers and mechanics working in the field of industrial automation, as they are most often used in air-conditioning systems for control cabinets. With customer feedback in mind, STEGO’s designers have introduced several improvements to the design of the mechanical thermostats.

One improvement is the relocation of the connection terminals from the bottom to the front of the device, meaning the user now has a direct access to the terminals. The terminals themselves have also been changed from traditional (screw) to self-clamping (spring) ones, which puts constant pressure on the leads and prevents them from becoming loose. This has the effect of shortening the assembly time, which is important in serial production.

The most visible change is the larger setting knob. Due to its size, the user can easily read the selected value and should be able to set the thermostat’s tripping temperature more accurately.

The thermostats remain compact devices (60 x 33 x 41 mm), available in a wide range of setting temperatures (both in °C and °F). They are approved by most important certification agencies — UL, VDE and EAC — and have an IP rating of IP20, with an operating temperature from -45 to +80°C.
