BYM6 New Energy Circuit Breaker Product Introduction
Baoyu Electric has developed the BYM6 Series High-Voltage Molded Case Circuit Breakers after years ofdedicated research into domestic and international new energy system operations and customer needs. These circuibreakers are desianed for high-voltage applications, with a rated voltage up to AC 1140V and a current rating up to800A.Under an Ac 800V voltage, the BYM6 series circuit breakers offer a breaking capacity of up to 36.5kA, ensuringreliable short-circuit protection for the system.Standards:lEC60947-1GB/T 14048.1:General ruleslEC 60947-2 GB/T 14048.1:Circuit breakers
High Voltage Compatibility: Rated for AC 1140V and compatible with 1140V DC/AC systems, the BYM6 Series supports modern high-voltage solar arrays, reducing energy loss and enhancing grid-tie efficiency.
Robust Protection Mechanisms: Equipped with overload long-delay protection and short-circuit instantaneous protection, it safeguards PV inverters, transformers, and distribution lines from damage, ensuring compliance with stringent safety standards.
High Breaking Capacity: Engineered for ultra-high breaking capacity (up to 36.5kA), this MCCB minimizes downtime by isolating faults swiftly, even in demanding industrial environments.
Compact & Durable Design: Featuring a shake-proof, compact structure and corrosion-resistant housing, it excels in harsh conditions, from offshore solar farms to desert installations.
BYM6 New Energy Circuit Breaker Product Features
The BYM6 Series operates as a critical safeguard in high-voltage AC 1140V photovoltaic systems, designed to interrupt fault currents during overloads, short circuits, or abnormal voltage conditions. Its core functionality revolves around:
Thermal-Magnetic Trip Mechanism:Thermal Protection,A bimetal strip responds to prolonged overcurrents (e.g., caused by equipment overload or insulation degradation). As temperatures rise, the strip bends, triggering a mechanical release to disconnect the circuit.
Magnetic Protection: A solenoid coil detects sudden current spikes (short circuits). When the current exceeds the predefined threshold (e.g., 10x the rated current), the magnetic force instantly trips the breaker, isolating the fault within milliseconds to prevent equipment damage or fire hazards.
Arc-Quenching Technology:The breaker’s molded case design incorporates arc chutes and splitter plates to rapidly cool and extinguish arcs generated during interruption. This ensures minimal downtime and enhances system longevity, even under extreme fault conditions.
PV-Specific Adaptations:High Voltage Compatibility: Optimized for AC 1140V systems, it supports the increasing voltage demands of modern solar farms and grid-tied inverters, reducing energy loss and improving transmission efficiency.
Environmental Resilience: Engineered to withstand harsh outdoor conditions, including temperature fluctuations (-25°C to 70°C) and UV exposure, ensuring reliable performance in solar installations

Choosing us means choosing quality
The heart of the circuit breaker holds the contact system. It stops the flow when there is too much power or short circuits. This keeps both the gear & folks safe. The design must take on full-bore flow. It should act fast if there's too much flow. If not, it may get too hot or break. The parts & build of the contact points need to be top notch. They should pass the flow well & be strong. This cuts flow block & makes them last long. The gears & wires in the breaker must sync well. They must cut the link well when there are faults. This cuts the risk of fires & gear break. It keeps the power system safe.
The arc-killing room is key too. It kills the arc & cuts off the flow. When the flow stops, an arc shows up at the touch points. The room stops the arc from getting big by keeping each end apart. It uses special stuff to cool the arc fast & stop the heat. This keeps the gear safe. It also stops stray flow, which keeps folks safe. By making the room well, the breaker works better & more safe. This ensures safe work in all states.
High flow stuff is key in all gear. This stops shocks & makes the power set-up firm. These stuff show tiny hold-back when flow goes through. This cuts the push-back from the flow. Big push-back in high stress can make the gear shake or break. Using good stuff keeps the flow fine & loses less flow. So, we get good flow & quickly guide faults along a safe way. This drops shock risk. By using good stuff in wires, the power set-up stays firm. This makes gear work well & safe when there's a big load. This ups how well gear works & keeps folks safe.
