    MasterPact NW and NT Circuit Breakers with Arc Flash Protection

    Industry-leading protection for personnel and equipment.

    The design of the new Masterpact NW arc flash-protecting circuit breaker is unique to the industry. The blow-open terminal is shaped so there is a reverse current loop at the moving arm. This reverse current flow creates a magnetic force that is proportionate to the amount of current.
