W-VACiMB Medium Voltage Mining Circuit Breakers

Mining circuit breakers (W-VACi-MB) are designed to protect transformers, capacitor banks, motors, busbar sections and cables. Featuring IEC ratings of 17.5 kV, they reliably switch normal load currents and high-stress fault currents. Compact circuit breakers are sealed, keeping out dust and contaminants prevalent in a mine environment, which extends the life of the circuit breaker and reduces maintenance time and costs. No external arcing enhances mining safety.
