(under subclass 13) Subject matter including means which are
automatically responsive to an abnormal or unsafe condition and either disables the system or corrects the abnormal or unsafe condition.
(1) Note. Examples of the conditions to which the systems of this subclass are responsive are: arc back, flash over, excess heating, short circuit, open ground, input voltage failure, failure of an element of the system, excess overload and underload.
(2) Note. The abnormal or unsafe condition may be in the converter device or in any other part of the system.
(3) Note. An example of the integral protection means is a zener diode which responds to an overload condition.
