Gas relay with pressure switch

Explanation to code 63B

For use on hermetically sealed transformers, the CF 38 gas relay is available with an optional pressure switch.
The pressure switch controls overpressure in the hermetically sealed transformer.
If the pressure exceeds the factory-set pressure range, a change-over contact is operated that can be used as an alarm or shutdown signal.
The switching pressure is factory set and can be selected within the setting range of 0.2 to 0.5 bar.

For the selection of switching pressure, see under special designs.

 

Construction

The principal construction of the gas relay with float and its electromechanical function are the same as those of the standard design.
