Description
The Suntree DC MCCB is a heavy-duty circuit protection solution designed for demanding direct current (DC) applications in solar energy systems, commercial solar farms, and industrial renewable energy installations. Tailored for high-current environments, it safeguards inverters, battery banks, and photovoltaic arrays from electrical faults with precision. Supporting voltages up to 1500V DC and adjustable current ratings (63A?1000A), it meets the needs of utility-scale solar projects, off-grid storage systems, and hybrid energy networks.
Constructed with a reinforced, UV-resistant thermoplastic case and silver-alloy contacts, the MCCB withstands harsh outdoor conditions, including temperature extremes (-40?C to +85?C), humidity, and chemical exposure. Its advanced magnetic-hydraulic trip mechanism ensures rapid fault interruption, minimizing downtime and equipment damage. Compliant with IEC 60947-2, T?V Rheinland, and RoHS standards, it adheres to global safety and environmental regulations for solar and industrial applications.
Key Features for Solar Professionals:
High Breaking Capacity: Up to 50kA short-circuit current rating, ensuring protection for large PV arrays and battery banks.
Modular Design: DIN rail or fixed-mount compatibility with adjustable trip settings (thermal/magnetic) for customizable protection.
Solar-Optimized: Zero voltage drop design, arc-quenching technology, and reverse polarity protection for DC systems.
Durability: IP65-rated enclosures for dust/water resistance, vibration-proof construction, and flame-retardant (UL94 V-0) materials.
