Heinemann Circuit Breakers Series GH_ The curves shown indicate the magnitude and duration of overloads which will be tolerated before tripping occurs. By selecting the proper curve, breaker response can be closely matched to the safe operating limits of the equipment or circuitry. Curve 1 allows the largest and most prolonged overload, needed to prevent nuisance tripping on motor circuits. Curve 2 a medium delay, accommodates mixed loads consisting of lights, motors, and resistive heating, where the breaker is rated to the wiring instead of to any specific load. Curve 3 permitting a very...
