Air circuit breaker VA-450 1600/1250A 3P 55kA fixed EKF mccb450-1600-1250

VA-45 v2 EKF automatic circuit breakers up to 6300A are designed for conducting current in normal mode and disconnecting overcurrents during short circuits and overloads (including single-phase ground faults) and are used in three-phase AC electrical networks with a voltage up to 690V and a frequency of 50 Hz. These circuit breakers are used as incoming automatic circuit breakers; for protecting electric motor circuits, as well as outgoing lines, including in MSB, Switchboards; in automatic transfer switch schemes with sectioning (on three circuit breakers) and without sectioning (on circuit breakers); for protecting outgoing lines on the low side of 10/0.4 kV transformer substations.
