Time/Current Characteristic Curves forWestinghouse Current Limit-R CircuitBreakers and Tri-Pac Circuit Breakers
WestinghouseAB DE-IONCurrent LimitingCircuit Breakers
Individual oversize copies of curves listedabove printed on onion-skin paper areavailable in limited quantity from:
Cutler-HammerWestinghouse &Cutler-Hammer ProductsFive Parkway CenterPittsburgh, PA 15220
When ordering onion-skin curves, use num-ber at bottom of page where curve appears,i.e., SC-4340-80. Requests for full sets ofcurves will not be honored.
Voltages shown in curve headings aremaximum at which the breaker may beapplied. Interrupting capacity of individualbreaker is tabulated on each curve.

When adjustable rating plugs are used, short delay pickup settingstrack the selected position of the adjustable rating plug. Forexample, with an adjustable 250 amp rating plug set at 50% andthe short delay pickup set at 4X, the short delay pickup is250 X 50% X 4 - 500 amps.
The threshold point changes with the ampere value of the ratingplug.
