ZJ Beny Molded Case 250A Circuit Breaker (MCCB)

The ZJ Beny 250A Molded Case Circuit Breaker (MCCB), likely from the BDM series (e.g., BDM-250), is a high-capacity DC breaker designed for robust protection in large-scale solar PV systems, battery energy storage systems (BESS), EV charging stations, and industrial DC applications. It provides reliable overload, short-circuit, and reverse-current protection with adjustable trip settings, ensuring safe and efficient operation in high-current environments. This MCCB is well-suited for integration with systems like the Ritar Must 3.2kW solar kit, offering enhanced safety for expanded solar arrays or battery banks.

Key Specifications

• Rating: 250A DC (top of the BDM series range, 80A–250A)
• Poles: 2P (bipolar for DC isolation; 4P options available for higher-capacity setups)
• Voltage: Up to 500V DC (supports high-voltage DC applications)
• Breaking Capacity: Up to 15kA (robust fault handling for extreme conditions)
• Power Supply: DC (optimized for minimal voltage drop and energy loss)
• Trip Mechanism: Adjustable for precise over-current protection; safeguards against overloads, short circuits, and infrequent operations
• Enclosure: IP65 (dust- and water-resistant, UV-protected for outdoor durability)
• Certifications: IEC 60947-2, GB/T 14048.2, TUV, SAA (meets global standards for solar and energy storage)

Features

• Efficiency and Durability: Engineered for harsh environments (–40°C to +85°C); minimizes arc flash risks and ensures long-term reliability in off-grid or renewable systems.
• Easy Installation: Compact design with DIN-rail or panel-mount compatibility; integrates into combiner boxes, inverters, or DC distribution panels.
• Protection Functions: Comprehensive protection against overloads, short circuits, reverse currents, and infrequent operations; ideal for large PV strings or battery banks in grounded/ungrounded systems.
• Applications: Protects high-current setups like large solar arrays (up to ~250A peak output), commercial BESS, EV charging infrastructure, and DC power systems.

Warranty & Support

• Warranty: 2 years (standard for ZJ Beny DC components)
• Availability: Stocked by global distributors like Solargen Technologies, Gridfree, or Solar Rains; in Kenya, check kreatives.co.ke for local pricing and professional installation. Spare parts are readily available through authorized suppliers.
