The transition from 1000V to 1500V systems requires advanced arc-quenching materials and magnetic blowout technologies. Our R&D focuses on thermal-magnetic coordination to ensure instantaneous tripping under critical fault conditions.
Meeting IEC 60947-2 and UL 489B standards is non-negotiable. Our products undergo rigorous testing in high-temperature ambient environments (up to 70°C) to simulate real-world solar farm conditions.

Selecting the right MCB for your solar installation is critical for long-term ROI and safety. Below is a comparison of DC MCB vs. AC MCB characteristics to highlight why specialized solar breakers are necessary.
| Feature | Standard AC MCB | Shuorui Solar DC MCB |
|---|---|---|
| Arc Quenching | Relies on zero-crossing points | Permanent magnets for rapid arc stretching |
| Voltage Rating | Up to 415VAC | Up to 1500VDC |
| Polarity Sensitivity | Non-polar | Optimized polar/non-polar designs available |
| Breaking Capacity | 6kA - 10kA | Up to 15kA (High-performance series) |
| Application | Residential Lighting/Power | PV Arrays, Inverters, Battery Storage |
Designed for compact DIN-rail mounting in home distribution boxes. Our 63A MCBs provide seamless integration with hybrid inverters and lithium battery banks.
Scalable protection for medium-sized arrays. Our SPD and MCB combinations ensure protection against both internal faults and external lightning surges.
High-voltage 1500VDC solutions for massive solar fields. Optimized for durability in harsh environments, from desert heat to coastal humidity.
Critical protection for BESS (Battery Energy Storage Systems) where high fault currents are a significant risk during discharge cycles.
By eliminating middlemen and leveraging local economies of scale, we provide premium quality at a 20-40% lower price point than European or North American brands.
Our in-house design team can customize trip curves, private labels, and packaging to meet your local market's branding and regulatory requirements.
From concept to sample in under 14 days. Our advanced CNC and automated assembly lines ensure that innovation never waits.
Real-time monitoring of current, voltage, and temperature via WiFi/RS485. Predict potential failures before they cause downtime.
Our WiFi Intelligent Reclosing series allows grid operators to remotely reset circuits after a transient fault, drastically reducing O&M costs.
AI-driven analytics to track the degradation of contacts based on breaking cycles and load intensity.
MCBs (Miniature Circuit Breakers) are typically used for currents up to 63A or 125A in residential and small commercial string protection. MCCBs (Molded Case Circuit Breakers) are used for higher current applications (up to 1600A) and higher breaking capacities, often at the inverter output or main combiner box level.
Standard AC SPDs are not designed to handle the continuous DC voltage found in solar arrays. In the event of a surge, an AC SPD may fail to extinguish the DC arc, leading to a fire hazard. DC SPDs use specialized MOV (Metal Oxide Varistor) technology and thermal disconnectors designed for DC extinction.
Yes, we offer comprehensive OEM and ODM services. This includes custom laser printing of your brand logo, specific electrical parameter tuning, and customized retail or industrial packaging.
Each batch undergoes insulation resistance testing, dielectric strength testing, and mechanical endurance cycles. We use high-grade fire-retardant materials (UL94-V0) and silver-plated copper contacts to ensure minimal contact resistance and maximum longevity.
Standard orders typically ship within 15-25 days. Sample orders can be dispatched within 7 days. Our proximity to Ningbo and Shanghai ports ensures rapid global logistics.
