The STEGO KTO 111 and KTS 111 are compact mechanical thermostats ideal for regulating heaters, filter fans, and heat exchangers in various industrial applications. These thermostats are designed for use up to 5,000 meters in altitude, ensuring reliable performance in challenging environments. The Push-In terminals allow for tool-free wiring, simplifying installation and maintenance. The KTO 111 model functions as a contact breaker (NC), opening the circuit when the temperature rises, while the KTS 111 acts as a contact maker (NO), closing the circuit when the temperature rises. They are suitable for applications requiring precise temperature control and reliable operation.
