APPARATUS, SYSTEMS, AND METHODS FOR OPERATION OF A TRIP UNIT IN A CIRCUIT PROTECTION DEVICE

Apparatus, systems, and methods for operation of an electronic trip unit are described. One example is a method for use in operating an electronic trip unit including a first controller. The first controller is configured to selectively operate a tripping device coupled between an input terminal and an output terminal of the electronic trip unit. The method includes receiving, by a second controller, a plurality of health signals from the first controller. The second controller determines an existence of an undesired condition based on at least one of the plurality of different health signals, and determines a first action to be taken to remedy the undesired condition.
