    • Advantages/Key Features
    1 Superior Performance
    The rotating double-break design effectively reduces the damage to the circuit caused by large current surges. The innovative new type of rotating shaft design effectively limits the thermal stress generated in the event of a short circuit
    2 Safety and Reliability
    The breaking capacity can reach 100kA, providing ultimate short-circuit protection for the circuit. The zero arc flash design can prevent phase-to-phase short circuits and ensure the safety of the equipment
    3 User-friendly
    A variety of installation and wiring methods make the product's layout and wiring in the cabinet more flexible. The modular design of accessories enables the realization of more protective functions within the same volume
