Circuit Breaker Ratings: LVPCB standard frame ratings
3200 to 6000
Circuit breaker ratings and application data per IEEE C37.06-2009 (medium/high-voltage power CBs) and IEEE Std 3004.5-2025 (low-voltage LVPCB and MCCB). Covers MV/HV preferred ratings (interrupting, TRV, close-latch), LV frame and trip-device ratings, LVPCB short-circuit ratings with and without instantaneous trip, X/R multiplying factors for fault-current derating, altitude derating factors, and MCCB electrical endurance operation counts.
