Technical Data - Thermostat B 30VDC:
Technical Data - Thermostat C 250VAC:
Monitoring of levels and temperatures of
liquids.
When the oil level decreases and the float
reaches the switching points, the contacts
will be actuated magnetically. The switching
positions of the contacts are maintained
until the float moves over them again by
virtue of the raising oil level.
A bimetal disc which can be influenced by
temperature is switching as soon as the
adjusted switching temperature is reached.
Thermostates with various switching temperatures and voltages are available (see
order designation).
