Appendix F. Circuit Breaker Repetitive Duty Data

General

Circuit breakers are designed primarily to perform the

function of circuit interruption under short-circuit conditions.

Nevertheless modern circuit breaker mechanisms are capable

of many operations under full-load operation and in-rush

conditions such as encountered in motor starting

applications. Industry standards have been established for

the minimum performance that is indicated in Table F-1.

With adequate maintenance, GE breakers can be expected to

exceed the standards.

Table F-1. Repetitive Duty and Normal Maintenance

Notes

Power operated circuit breakers, when operating under usual

service conditions, shall be capable of operating the number

of times specified in Table F-1. The operating conditions and

the permissible effect of such operations upon the breaker are

given in the following lettered paragraphs. For each column,

all paragraphs listed in the column heading must be given

consideration.
