    Wherever high short-circuit current is involved Masterpact UR takes control As installed power increases, electrical distribution has to shift from LV design to a MV design.
    Built from the highly reliable standard air circuit-breaker, Masterpact UR has been developed to allow much higher installed power with LV design.
    Best advantages:

    • Cost effective solution
    • No MV needed, easier maintenance
    • Simpler solution, reduced time to market.


    Specific applications:

    • Busbars coupling onboard merchant vessels, off-shore platform
    • Loop networks in industry, cement plant - petro-chimic industry
