Featuring an innovative non-polar design, it adapts to any current direction and meets the flexible layout requirements of photovoltaic confluence and energy storage systems. Among the series, the HUB9NEZ-80has obtained the stringent UL489 certification, serving as a reliable safety guardian for commercial, industrial and residential energy storage scenarios.
HUM9NEZ DC Molded Case Circuit Breaker It supports a maximum voltage of DC 1500V and boasts advantages including low internal resistance, low power consumption and low temperature rise. An IP65 handle is optional, specifically designed for application scenarios with high protection requirements (such as photovoltaic combiner boxes and high-voltage boxes). It provides DC 1500V high-protection products for the power generation/energy storage side and supports a high breaking capacity of 20kA.
HUW9NEGZ DC Air Insulated Isolating Switch At this exhibition, the key promoted product is the HUW9NEGZ-4000 frame-type DC isolating switch, which adopts 2P technology (DC 1500V) and its volume is significantly reduced to 60% compared with the traditional 4P solution ! This breakthrough design perfectly solves the space limitation problem in high-density energy storage scenarios such as PCS boost integrated machines, and becomes the key to efficient system integration.
HUW9NE DC Air Circuit Breaker & HUW9NE DC Air Circuit Breaker It provides high-voltage and high-breaking-capacity protection for box transformer systems of large-scale power stations, ensuring stable grid-side connection and system safety. It is widely applied to power generation-side protection and grid connection links.
Most products of the NE New Energy Series have obtained authoritative international and domestic certifications including TÜV, CE, CB and CCC, serving the new energy industry with global quality standards.
Empowering PV and Energy Storage Applications
Huanyu Electric deeply understands the differentiated needs of different application scenarios and focuses on presenting two core solutions at this exhibition.
