Notes:
1 Maximum voltage for which the breaker is designed and upper limit of operation.
2 Available current ratings are 1200A, 2000A, 3000A, 3500A and 4000A. 4000A rating is forced-air cooled, indoor constrcution only.
3500A is available in outdoor construction, but must be derated to 3250A.
3 At system operating voltages equal to or less than rated maximum voltage.
