The STEGO KTO 111 and KTS 111 are compact mechanical thermostats designed for reliable temperature regulation in various industrial applications. These thermostats are ideal for regulating heaters, filter fans, and heat exchangers, as well as switching signal devices when a temperature limit is exceeded. Featuring Push-In terminals for tool-free wiring and a robust design suitable for altitudes up to 5,000 meters, these thermostats offer ease of use and durability. The KTO 111 model functions as a contact breaker, opening the circuit when the temperature rises, while the KTS 111 acts as a contact maker, closing the circuit when the temperature rises. They are suitable for use in a wide range of environments and applications requiring precise temperature control.
