Specification
Stem thermostats TH 260, TH 261 are temperature-dependant singlepole switches, designed for protection against excessive exhaust gas temperature of diesel aggregate used for diesel-electric train heating. They may also be used for other thermoregulation.
Core of these thermostats is a reliable mechanical system, that has no power consumption itself. They are known for significantly low operational and maintenance costs compared to electric systems.
Temperature dilation of the tube is transfered by invar bar and lever gearing onto the switching mechanism, which is enclosed in a waterproof head. There are two feet with screw holes designated for thermostat mounting.
