Application
Combiner Box
As a critical protective component for combiner boxes (especially in solar PV systems), the SRB3DC-63 DC MCB is perfectly adapted to the high-voltage DC environment of combiner boxes. With 1P-4P configurations (up to DC1000V) and 10kA short-circuit breaking capacity, it effectively safeguards the internal circuits of combiner boxes against overloads and short circuits. Its reliable fast-break technology ensures timely power cutoff, protecting the combiner box and connected PV modules from damage, while CCC, CE, and TUV certifications guarantee compliance with safety standards for new energy systems.
Cable Branch Box
Tailored for cable branch boxes in industrial and distribution networks, this DC MCB meets the diverse protection needs of branched DC circuits. Covering a current range of 6A-63A and supporting ≤25mm² wiring capacity, it seamlessly integrates with cable branch box configurations, stabilizing power distribution among multiple branch lines. The IP20 dust-proof and finger-proof design, combined with durable flame-retardant housing, ensures long-term reliable operation even in complex industrial environments, preventing risks such as line overheating or short-circuit fires.
Drawer Cabinet Cable
Designed for the cable protection of drawer cabinets (a key part of low-voltage distribution systems), the SRB3DC-63 DC MCB offers easy installation via standard 35mm DIN rail, perfectly matching the mounting requirements of drawer cabinet internal structures. With 20,000 mechanical life cycles and 1,500 electrical life cycles, it withstands frequent on-off operations of drawer cabinet cables. Its rated insulation voltage of DC1000V and 4kV impulse withstand voltage provide comprehensive insulation protection, ensuring the safety and stability of power transmission through drawer cabinet cables in industrial or commercial distribution scenarios.
