KTO 111 / KTS 111 Small Compact DIN Rail Thermostat

The mechanical thermostats KTO 111 and KTS 111 are two state regulators for use up to 5,000 meters in altitude, thanks to optimized air gap and increased creepage distance. The conductor can easily be connected via Push-In clamps without tools.

KTO 111: Thermostat (NC); contact breaker for regulating heaters. The contact opens when temperature is rising.
KTS 111: Thermostat (NO); contact maker for regulating of filter fans and heat exchangers or for switching signal devises when temperature limit has been exceeded. The contact closes when temperature is rising.
