Legrand DMX³ 2500 Circuit Breakers and DMX³-I 2500 Trip-Free Switches

1. Use

DMX³ air circuit breakers provide optimal solutions for protection requirements in low voltage electrical installations (IEC/EN 60364-1) up to 6300 A. Their electric and mechanical robustness, breaking capacity, and accessorizing options make them suitable for demanding applications. The DMX³ series also includes trip-free switches (I series) offering high performance in insulation, robustness, closing, and withstand capability. Both series are designed for increased continuity of service, energy efficiency, and environmental considerations.
