DEFINITION

Classification: 361/91.7

Protection by snubber circuitry:

(under subclass 91.1) Subject matter wherein fault removal includes auxiliary circuitry which limits the rate-of-rise of voltage or current utilizing circuitry or circuit element such as RC, diode, transistor and/or inductor arrangements, individually or in combination therewith.
