Molded Case Circuit Breaker 3p 3200/3200A 100kA VA-45 PROxima fixed EKF mccb45-3200-3200

VA-45 to 6300A series automatic circuit breakers are designed to carry current under normal conditions and disconnect 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 Main Switchboards (MSB), Distribution Boards (DB); 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.
