The STEGO KTS 111 is a mechanical thermostat and regulator suitable for a variety of industrial applications, including regulating filter fans, heat exchangers, and switching signal devices. It utilizes a thermostatic bimetal sensor and snap-action contact for reliable temperature control. The device is designed for use in harsh environments, with a wide operating temperature range and protection up to 5,000 meters altitude. Push-In terminals allow for tool-free wiring and constant pressure on the wires, preventing loosening during transport. It is ideal for applications requiring precise temperature regulation and robust performance.
