WebIt is current (r.m.s.) that a circuit breaker is capable of breaking at given recovery voltage and under specified conditions (e.g., power factor rate of rise of restriking voltage). The … Frequency rating specifies the operating frequency of a circuit breaker. Normally, typical circuit breaker sizes are rated 50 Hz or 60 Hz and are occasionally used in DC or direct current. Using a circuit breaker that is not within its operating frequency may cause a temperature rise and damage to the unit. See more The circuit breaker voltage rating refers to the highest RMS voltage (Root Mean Squared) for which it is built. Some circuit breakers have more than one voltage number on their nameplate. You can tell the actual voltage … See more Continuous current rating is the highest current a circuit breaker can take continuously on an operating frequency while maintaining its good condition. This rating reflects the … See more The maximum current that a circuit breaker can conduct at the point of closure is its making capacity. This specification applies to short circuitswhen the breaker contacts close. See more There are two types of breaking capacity, the Symmetrical and Asymmetrical kind. Each has its own characteristics. Symmetrical … See more

WebConsider the example of an electric motor with a service factor of 1.15 and a full load amperage rating of 25 A. The circuit breaker needed for this application should be sized as follows: Since the overload current rating cannot be greater than 125% of the FLA, engineers can choose the next lower circuit breaker rating, for example, 31 A. WebAnthony, circuit breakers are rated for each individual phase or leg.
