Dual-Fused Combiner Box is developed by Junda to provide enhanced protection and reliable power aggregation for photovoltaic systems. This solution is designed for solar power plants and commercial PV installations where higher safety standards and stable long-term operation are required. The dual-fused design integrates fuses on both the positive and negative poles, effectively improving protection against overcurrent and short-circuit conditions. This configuration helps isolate faults more precisely, reducing the risk of cascading failures and enhancing overall system safety. By offering balanced protection on both polarities, the combiner box supports safer operation in complex and high-capacity PV systems. Key Features of Dual-Fused Combiner Box is built with high-quality DC fuses, circuit breakers, and surge protection devices to ensure consistent electrical performance under demanding conditions. The enclosure is constructed from durable, weather-resistant materials, providing strong resistance to dust, moisture, and UV exposure. This allows reliable outdoor operation in environments with high temperatures and varying climate conditions.

The Junda Dual – fuse PV Combiner Box is compliant with NEC 2017/2020 and is used to combine per string up to a 35A fuse – link (1500V – specific PV fuse, both positive and negative terminal), output circuit breaker rat ing 400A or 500A. In a photovoltaic power generation system, a device that combines several PV string parallel for one output. Used between PV modules and inverter. NEMA 4X enclosure ratings, meeting the outdoor in stallation and usage requirements. Installation and maintenance simple, convenient, it has a long service life.
Millions of factories. Only the premium ones on Pinpoki. We verify them, so you don’t have to.
Searching for a good manufacturer on big B2B platforms means sorting through millions of listings, most of them trading companies and unproven suppliers. Pinpoki skips that. We only work with premium manufacturers, so you start from a shortlist of factories worth your time.
Every factory on Pinpoki is handpicked and personally verified by our team. We check real production capability, certifications, and compliance with international standards before a factory is listed. You don’t need to fly to China, hire an auditor, or run your own background checks. We’ve done that work for you.
Once your order is confirmed, we coordinate the rest: communication with the factory, payment, and shipping to your region. One team, one point of contact, no guesswork.
