Какво е обикновено отворено (Не) Термостатен превключвател KSD301?
The Thermostat Switch KSD301 bimetallic disc operates in a Normally Open (Не) configuration. This means the circuit is initially open (изключен) at normal temperatures. When the temperature rises to a predefined threshold, the bimetallic disc bends, closing the circuit and allowing current flow.
