Low voltage circuit breaker ratings
Web28 sep. 2024 · The industry defines frame as the maximum current rating of a circuit breaker of a particular construction. Breaker families are called “frames” such as P frame, R frame, W frame, etc. Frame is also used to indicate the maximum setting possible for a particular circuit breaker. For example, a PJ800 or PJ1200, or a 2000 A or 4000 A frame. Web5 mrt. 2016 · Some circuit breakers have what is referred to as a “slash” voltage rating, such as 120/240 volts.In such cases, the breaker may be applied in a circuit where the nominal voltage between any conductor and ground does not exceed the lower rating and the nominal voltage between conductors does not exceed the higher rating.
