Inductive Ratings
Targets
Electronically latched, manually reset target indicators may be optionally selected as either internally
operated or current operated.
Current operated targets require a minimum trip circuit current of 200 milliamperes and have a continuous
rating of 3 amperes, a two-minute rating of 7 amperes, and a one-second rating of 30 amperes.
Internally operated targets should be selected if the relay has normally-closed output contacts.
