STEGO KTO 111 and KTS 111 mechanical thermostats are compact regulators suitable for a variety of applications, including heaters, filter fans, and heat exchangers. These thermostats are designed for use in challenging environments, with optimized air gaps and increased creepage distance allowing operation up to 5,000 meters in altitude. The Push-In terminals enable tool-free wiring and provide a secure connection, preventing wires from loosening during transport. The KTO 111 model functions as a contact breaker, opening the circuit when the temperature rises, while the KTS 111 model acts as a contact maker, closing the circuit when the temperature rises. They are ideal for industrial applications requiring reliable temperature regulation in demanding conditions.
