Voltage activated bimetal operated time delay relay with changeover
contact and snap action mechanism, excitation circuit and switching
circuit electrically separate, operation independent of mounting attitude.
High shock resistance. Delay times can be factory-preset as desired.
The continuous excitation voltage may be up to 1.4 times the rated
value. To shorten the switching time the excitation voltage may be
increased to 3 times the rated value but only for that switching time
period.
