Breaker current rating
Webinterrupting current values for various voltage rating and amp rating circuit breakers. Table 1 shows the single-pole short-circuit current values (from Table 7.1.7.2 of UL 489) for which all three-pole circuit breakers are tested and evaluated under single-pole interrupting capabilities. The far right column of 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 … 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 breaker’s thermal design in that the device … 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 breaking capacity defines the circuit breaker’s … See more
