Key Features：

DC 2000V / 630A High-Capacity Switching

Designed for next-generation photovoltaic and energy storage systems, the BH-630H supports up to 2000V DC and 630A, meeting the requirements of high-power solar installations and large-scale battery energy storage projects. The DC-PV2 utilization category ensures reliable load switching under demanding DC operating conditions.

Reliable DC Isolation for Maximum Safety

The switch provides safe electrical isolation during equipment maintenance, emergency shutdowns, and system servicing. Advanced arc-extinguishing technology minimizes arcing during switching, helping improve personnel safety and protect valuable electrical equipment.

Flexible Installation Options

Available with front-mounted, side-mounted, and external operating mechanisms, the switch can be easily integrated into combiner boxes, inverter cabinets, ESS enclosures, and customized electrical panels, simplifying equipment design and installation.

Full-Rated Current without Derating

Optimized contact design keeps the temperature rise to only 40K at the rated current of 630A, complying with IEC and GB standards. This enables continuous operation at full load without current derating, improving overall system efficiency and reliability.

Low Auxiliary Power Consumption

The motorized operating mechanism requires only 40W during operation, reducing auxiliary energy consumption while ensuring fast and reliable switching performance.

Designed for Harsh Environments

Engineered for demanding outdoor applications, the BH-630H operates reliably in ambient temperatures up to +70°C and installation altitudes of 5,000 meters, making it suitable for desert solar farms, mountain PV plants, and other challenging environments.
