On April 19, 2021, BH series photovoltaic energy storage dc disconnect switches were awarded the first UL98B certificate in China at the electronica China 2021 in Shanghai. The BH-250 PV disconnect switches have very high requirements in terms of electrical life, overload capability at very high ambient temperatures and flame resistance.
The BH-250 PV DC disconnect switches are suitable for use in power systems with rated voltages DC 1500V and below and rated currents of 250A and below, and can be used for infrequent connection and disconnection to isolate and disconnect lines and provide safety isolation for various low voltage circuits in the PV field. BH-250 PV disconnect switches are 2-pole 1500V, 250A and meet the latest PV2 standard. The BH-250 DC disconnector can be used in safe and reliable operation (-25 to +55°C) without any capacity reduction, and are available in a wide range of specifications and modular design solutions.
Since its inception, ZJBENY has focused on the development and innovation of photovoltaic components and is determined to be the benchmark in the PV reserve equipment industry. The BH-250 DC disconnect switch was awarded the first UL98B standard certificate in China, which will further promote the ZJBENY’s independent innovation, independent research and development process. ZJBENY always demands high standards for itself, providing the safest and most reliable guarantee for the photovoltaic power generation system and achieving the double guarantee of capacity and quality.
