NDW2

The NDW2 Series Universal Circuit Breaker is designed for power distribution networks operating at AC 50Hz/60Hz, with a rated current range of 200A to 6300A, rated insulation voltage of 1250V, and rated working voltages of AC220V/230V/240V, AC380V/400V/415V, AC440V/480V, and AC660V/690V. The NDW2-4000 and NDW2-6300 models are also applicable in networks with rated working voltages of AC800V, AC1000V/AC1140V (rated insulation voltage 1250V). It is used for distributing electrical energy and protecting lines and power supply equipment from hazards such as overload, undervoltage, short circuit, and single-phase earth faults, while also serving as a disconnector switch. The circuit breaker offers multiple protection functions, enabling highly accurate selective protection while avoiding unnecessary sudden power outages, thereby enhancing the reliability and safety of the power supply system.
