STEGO KTO 111 and KTS 111 mechanical thermostats are robust regulators suitable for use in demanding environments up to 5,000 meters in altitude. These thermostats utilize optimized air gaps and increased creepage distances for enhanced safety. The Push-In terminals simplify wiring, allowing for tool-free connections and constant wire pressure. The KTO 111 acts as a contact breaker for heaters, opening the circuit when the temperature rises, while the KTS 111 functions as a contact maker for filter fans, heat exchangers, or signal devices, closing the circuit when the temperature rises. They are ideal for applications requiring reliable temperature regulation in industrial settings.
