Air circuit breaker 4p H 4000A 125kA TT withdrawable with accessory kit ARMAT IEK AR-ACB-4VH-125-4000A-TTCF

Please note - in order to improve Customer convenience, we are transitioning from horizontal to vertical busbar connection for frame sizes G and H in the basic configuration. In ACB ARMAT data for frame sizes manufactured from February 2025 (batch 2502), vertical connection is used. Since we have single units of ACB ARMAT frame sizes G and H oriented for horizontal connection in stock - please consult with us before placing an order. ARMAT series Air Circuit Breakers (ACB) are designed to protect power supply networks from short circuits and overloads, as well as for the rapid switching of electrical circuit sections, and are designed for use in electrical installations with a rated operating voltage of up to 690 V and rated currents from 630 to 6300A. These circuit breakers are equipped with electronic trip units with various combinations of functional features, including Modbus communication capability, which, given a breaking capacity of up to 150 kA, allows the use of ACB ARMAT in any type of industrial and civil facilities. Compliant with GOST R 50030.2.
