Designed With Worker Protection In Mind

Power-Zone 4 switchgear is the benchmark in safety and reliability, whether you choose a Power-Zone 4 arc flash unit, or a standard unit with selected features designed to improve worker safety.

Power-Zone 4 AR (Arc Resistant) increases employee protection, while offering proven reliability, low maintenance requirements, and additional levels of arc flash prevention. In accordance to IEEE C37.20.7 our unique arc-containing design is engineered to provide superior strength and shielding, enhanced worker protection, and incident reduction features – while maintaining the smallest footprint on the market.

Arc Flash and Electrical Protection

Power-Zone 4 switchgear offers a wide range of arc flash mitigation options to fit your personal protective equipment (PPE) and operational requirements in standard designs.

  • Circuit Protection

    Masterpact circuit breakers have the highest short circuit ratings in the industry. Couple that with ease of maintenance, multiple interlocking options, and clear breaker status indication - Masterpact circuit breakers redefine electrical distribution protection.

  • Remote Racking Device

    The remote racking device allows the circuit breaker to be racked in or out while the worker operates the device from outside of the arc flash boundary.

  • Arc Flash Training

    When working on any electrical equipment, proper techniques must be followed to ensure worker safety. From wearing proper PPE, to following safety practices such as lock-out tag-out procedures, it is important to make these practices second nature. Take a class specifically designed for teaching you to operate switchgear following correct safety practices.
