Solar ACB

Different from ordinary circuit breakers, this Solar ACB is optimized for harsh photovoltaic working conditions. It stably adapts to AC voltage fluctuation, frequent switching, high and low temperature changes and outdoor severe weather, avoiding common problems such as false tripping, contact ablation and short service life in solar circuit application.

Equipped with comprehensive protection functions, the breaker provides reliable overload inverse time protection, short-circuit instantaneous & short-delay protection, and earth fault protection. Optional under-voltage & over-voltage protection and residual current protection meet diversified safety requirements. With high dielectric strength and high breaking capacity, it effectively resists sudden short-circuit current of PV loops, fully protecting inverters, grid connection lines, distribution cabinets and electrical equipment.

Made of high-strength flame-retardant housing material, the unit features dust-proof, corrosion-resistant and wide temperature adaptability, suitable for indoor cabinet installation and outdoor waterproof cabinet use. Multiple pole types including 2P,3P and 4P are available with complete current specifications. It adopts flexible wiring structure and sensitive operating mechanism to ensure long mechanical and electrical service life.

Manufactured in strict accordance with international low voltage standards, supported by our own factory production and quality control, customized specifications and OEM / ODM service are available. It is an essential core component for safe power distribution, circuit isolation and stable operation of solar AC systems.

• It avoids common defects of ordinary breakers such as false tripping and easy burnout.
• Built-in complete overload, short circuit and earth fault protection greatly secures inverters, ACDB cabinets and the whole PV equipment, reducing circuit failure risk and daily maintenance cost.
• Featuring wide temperature resistance, dustproof and anti-corrosion performance, it runs stably both in indoor distribution rooms and outdoor power stations.
• With complete specifications, simple installation and reliable factory quality support, it can be customized for various solar projects, delivering long-term cost-effective and safe power distribution protection for your photovoltaic system.

1.Installation and operation must be completed by professional electricians. Check model, rated voltage, current and breaking capacity before installation, and confirm no damage on housing, mechanism and terminals.
2.Install in standard vertical position. Reserve heat dissipation space inside cabinet and keep good ventilation to avoid overheating.
3.Adopt standard top-in and bottom-out wiring. Fasten cable terminals with proper torque, distinguish phase line and neutral line, and ensure reliable grounding.
4.Daily operation: push the handle upward for closing, pull downward for opening; operate gently without forced action.
5.The breaker will auto trip under overload or short circuit. Inspect PV lines and inverters thoroughly, remove faults and reset before reclosing.
6.Conduct regular cleaning and wiring inspection. Do not overload operation, forced closing with faults or private disassembly.
7.Equip with protective cabinet for outdoor installation, anti-dust, waterproof and anti-corrosion, suitable for long-term PV system operation.
