Circuit Breakers High current fully magnetic

Heinemann Circuit Breakers Series GJ Versatile, compact circuit breakers Heiremann" Series GJ circuit breakers are the logical choice lor high quality service entrance and panelboard installations, as well as control and protection ol commercial and industrial lighting, transformers, motors and power supplies. Their precisely tailored time delays, and ability to interrupt high currents makes them ideal for critical applica- tions with inductive or olher loads of up to 250 amperes. On overloads exceeding 1000-1400% of rating the time delay is bypassed, and the breaker operates instantly...

Heinemann Circuit Breakers Series GJ Time delay curves 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:...
