Product Description

The NDW3-4000 offshore wind power universal circuit breaker (hereinafter referred to as the circuit breaker) is suitable for AC 50/60Hz, rated current of 800A~4000A, rated insulation voltage of AC1250V, rated operating voltage of AC220/230/240V, AC380/400/415V, AC440/480V, AC660/690V, AC800V, AC1000V, AC1140V distribution networks. It is used to distribute electrical energy and protect lines and power equipment from hazards such as overload, undervoltage, short circuit, single-phase grounding, etc. It also has isolation function. The circuit breaker has multiple protection functions, achieving high-precision selective protection while avoiding unnecessary sudden power outages, thereby improving the reliability and safety of the power supply system. This product is mainly suitable for the offshore wind power application in the new energy industry, meeting the harsh conditions of high salt spray, high corrosion, and high humidity and heat at sea.The NDW3-4000 offshore wind power universal circuit breaker (hereinafter referred to as the circuit breaker) is suitable for AC 50/60Hz, rated current of 800A~4000A, rated insulation voltage of AC1250V, rated operating voltage of AC220/230/240V, AC380/400/415V, AC440/480V, AC660/690V, AC800V, AC1000V, AC1140V distribution networks.
