ZJ Beny Molded Case 200A Circuit Breaker (MCCB)

The ZJ Beny 200A Molded Case Circuit Breaker (MCCB), typically from the BDM series (e.g., BDM-200), is a high-performance DC breaker optimized for robust protection in large-scale solar PV systems, battery energy storage systems (BESS), EV charging infrastructure, and UPS setups. It delivers overload, short-circuit, and infrequent operation protection with anti-reflux features, ensuring safe isolation in high-current DC environments. This model is an excellent match for scaling up systems like the Ritar Must 3.2kW solar kit, providing reliable overcurrent safeguarding for expanded arrays or battery banks.

Key Specifications

• Rating: 200A DC (within the 80A–250A BDM series range for scalable protection)
• Poles: 2P (bipolar for efficient DC isolation; 4P variants available in the series)
• Voltage: Up to 500V DC
• Breaking Capacity: Up to 15kA (high short-circuit rating for fault handling in demanding conditions)
• Power Supply: DC (low voltage drop design for minimal energy loss)
• Trip Mechanism: Adjustable for precise over-current response; includes overload and short-circuit safeguards
• Enclosure: IP65 (UV-resistant, dust- and water-tight for outdoor durability)
• Certifications: IEC 60947-2, GB/T 14048.2, TUV, SAA (compliant for solar, energy storage, and global standards)

Features

• Efficiency and Durability: Tested for extreme temperatures from –40°C to +85°C; rugged construction minimizes arc flash risks and ensures long-term reliability in off-grid or renewable applications.
• Easy Installation: DIN-rail or panel-mount ready; compact 2P footprint integrates seamlessly into combiner boxes, inverters, or distribution panels.
• Protection Functions: Comprehensive coverage against overloads, short circuits, reverse currents, and infrequent operations; ideal for positive/negative PV strings in grounded or ungrounded setups.
• Applications: Safeguards large solar arrays (e.g., up to ~200A peak output), commercial BESS, EV stations, and DC power cabinets.

Warranty & Support

• Warranty: 2 years on the unit (consistent with ZJ Beny DC product standards).
• Availability: Widely stocked by global distributors like Gridfree, Solargen Technologies, and Solar Rains; in Kenya, check kreatives.co.ke for local pricing and installation. Spare parts are readily accessible through authorized channels.
