Finkl Steel® has resolved long-standing production and maintenance issues at its Canadian facility in Sorel, Quebec, since switching up to ABB’s VD4-AF1 vacuum arc furnace circuit breaker.
The VD4-AF1 is the first medium-voltage (MV) circuit breaker with servomotors, which enables precise drive control and eliminates the need for inrush limiting reactors and resistances for applications up to 38kV, leading to significant cost and space savings. It also brings 24/7 predictive health indication and accurate synchronization with network voltage, to control the accuracy and precision of the electrical current passing through the furnace, while reducing the risk of component failure and enhancing safety. VD4-AF1 arc furnace breaker has much greater longevity and endurance, slashes maintenance costs and brings added technological benefits.
