High-performance low-voltage protection units manufactured in state-of-the-art Chinese manufacturing facilities. Precision engineered for solar arrays, massive central inverters, and heavy-duty industrial switchgear systems.
In utility-scale Photovoltaic (PV) power systems and high-density Battery Energy Storage Systems (BESS), efficiency optimization dictates a transition towards higher operating voltages. The traditional 400V and 690V AC topologies are rapidly giving way to 800V AC configurations. Elevating the voltage reduces current parameters ($I = P / (\sqrt{3} \times V)$), allowing electrical design engineers to radically downsize copper conductor cross-sectional areas. This achieves a reduction of up to 40% in cable transmission losses ($I^2R$).
However, switching at 800V AC incurs severe technical challenges: intensified dielectric stress, high arc energy generation, and rapid thermal cycling. To counter these challenges, Thermal Magnetic 800V MCCBs must be deployed as high-breaking-capacity gatekeepers. Designed inside specialized factories, these breakers integrate advanced bimetallic overload strips and dynamic magnetic trip mechanisms to withstand rugged industrial duties while providing robust fault clearing capabilities.

Acereare Electric, founded in 2015, possesses two wholly-owned manufacturing subsidiaries: RuiRui Electric and KeRui Electric. As a leading original equipment manufacturer (OEM) and original design manufacturer (ODM), Acereare Electric integrates state-of-the-art research, development, assembly, and strict quality control protocols across low-voltage power products, specialized Molded Case Circuit Breakers (MCCB), and Air Circuit Breakers (ACB).
Our heritage spans over 20 years of technical expertise inherited across generations, establishing our factory as one of China's premier ODM entities. Powered by automated assembly structures, high-fidelity testing labs, and robust client relations, Acereare collaborates with nearly 100 high-end domestic and global corporations to deliver industrial-grade overcurrent and short-circuit protection gear.
Deploying 800V MCCBs requires deep design alignment with thermal and electromagnetic forces. Designers face a choice between Thermal Magnetic trip systems and Electronic Trip Units (ETU/LSIG). Here is how they operate under 800V conditions:
Utilizes an accurately calibrated bimetallic strip (composed of two bonded metals with differing coefficients of thermal expansion). When continuous overcurrent occurs, resistive heating bends the strip, triggering the mechanical latch. At 800V AC, internal ambient temperatures can rise rapidly, requiring precise compensation structures inside the factory.
An electromagnetic armature trips instantaneously during high-current short circuit events. High-voltage grids can generate extremely destructive fault currents. Acereare’s magnetic trip points are fully adjustable, enabling perfect alignment with upstream and downstream selectivities, mitigating nuisance tripping.
800V AC faults produce highly volatile, elongated arcs. Our factories employ specialized gas-dynamic arc chutes containing multiple de-ionizing steel plates. These components partition the primary arc into tiny segments, cooled instantly by thermal dissipation channels to prevent phase-to-phase flashovers.
