Specification
Stem thermostates are temperature-dependent single-pole switches based on the principle of different temperature expensibility of metals. They are designed for electric circuit switching, however not as the main switch. The core of these thermostats is a reliable mechanical system, that does no power consumption itself.
Compared thermostats THS is used here higher protection IP 65 / IP 54.
Thermostats THS3, THS4 are supplied with a process connection using a union nut G1/2. They are known for significantly low operational and maitenance costs compared to electric systems.
