High breaking capacity & adjustable parameters for demanding switchboard configurations
Established in 2015, Acereare Electric operates as a premium original equipment manufacturer (OEM) and design manufacturer (ODM) with two wholly-owned sub-entities: RuiRui Electric and KeRui Electric. Spanning generations of profound electrical engineering expertise inherited over 20 years, we integrate cutting-edge Research & Development, raw metal fabrication, and advanced assembly processing lines under one unified quality management standard.
Our strategic factories specialize in Air Circuit Breakers (ACB), Molded Case Circuit Breakers (MCCB), and custom precision components. As a core supplier to high-end infrastructure and industrial automation grids across Europe, South America, the Middle East, and Asia, we empower global distributors with certified reliability and competitive cost structures.
By operating our own casting, metal stamping, and molding facilities, we guarantee complete control over components, from individual micro-contacts to the complete assembled breaker casing.
Understanding structural design choices, thermal performance, and substation safety criteria
When designing low-voltage switchboards, electrical power distribution systems, or main switchgear panels (MSB), selecting the appropriate installation format of your Air Circuit Breaker (ACB) is critical. The design selection dictates maintenance efficiency, installation footprint, thermal dissipation, and budget parameters.
In a Fixed Switch ACB configuration, the circuit breaker body is directly bolted onto the switchgear chassis and busbar system. The main copper terminals are mechanically connected to the feeder busbars. Fixed ACBs are highly cost-efficient, have fewer mechanical joints, and are ideal for critical processes where standard isolation switches are deployed upstream.
A drawout ACB features a chassis guide framework (drawer housing) allowing the breaker to be physically racked in or racked out. It features isolated secondary terminals, shutter barriers, and structural mechanical interlocks. This facilitates rapid breaker swap-out and maintenance without shutting down the entire panel board, albeit at a higher capital cost.
Both fixed and drawout options from our factory are armed with advanced LSIG electronic trip releases. These monitor Overload (L), Short-Time Delay Short Circuit (S), Instantaneous Short Circuit (I), and Ground Fault (G), allowing engineers to program precise protection curves for local utility mandates.
Why global switchboard builders and EPCs choose Acereare Group
Unlike standard assembly-only vendors, Acereare Electric controls 100% of the key components supply chain. Our manufacturing campus integrates multiple specialized workshops: mold tooling design, metal stamping and stamping parts processing, contact system fabrication (including copper and silver contact plates), and final electronic trip controller assembly. This structural advantage dramatically reduces material overheads and guarantees consistency across high-volume production batches.
Quality is tracked at every milestone through modern software systems: PLM (Product Lifecycle Management), MES (Manufacturing Execution Systems), and ERP (Enterprise Resource Planning). Our certified laboratory utilizes over 150 dedicated testing instruments and features 20+ specialized QC inspectors. We execute short-circuit calibration, dielectric breakdown tests, mechanical endurance fatigue simulations, and precise temperature-rise validation to meet IEC 60947 compliance.
Comprehensive ODM/OEM manufacturing processes developed for global scalability
One-stop manufacturing deploying six major processing technologies, heavy-duty stamping machinery, and over 10 automated and manual high-volume assembly lines.
A dedicated force of over 50 R&D engineers utilizing advanced 3D CAD modeling software. We pioneer 50+ new electrical and mechanical patents annually.
Operating two distinct factories optimized for complete products and accessory sub-assembly. Integrated via U8 & ERP systems for precise lead-time control.
Multi-stage incoming raw inspection and outgoing tests. In-house calibration ensures zero-defect rates across complex circuit breakers.
Adapting switchgear technology to withstand challenging environments and critical sectors
Engineered using low-temperature resilient polymers and custom-blended lubricants. Thickened corrosion coating guarantees flawless mechanical operation in cold-storage facilities and sub-arctic grid installations.
Our breakers withstand up to 72 hours of constant salt spray exposure for the complete unit. Designed for docks, shipyards, marine vessels, and offshore wind platforms to prevent galvanic corrosion of contacts.
At altitudes exceeding 2000 meters, thin air reduces heat dissipation and dielectric insulation. We apply calculated derating factors to the voltage and current capacity, ensuring safe high-elevation operation.
Optimized MCCB frameworks prevent domestic panel board damage, protecting HVAC systems, lighting arrays, and main elevators from overload anomalies and dangerous short-circuit faults.
Tested in constant 55°C environmental chambers. Controller cards are layered with thermo-protective compounds, and structural copper terminals are up-sized to minimize internal heat generation.
Integrated with high-precision current transformers, microprocessor-based protection controllers, and open Modbus RTU protocols for smart edge-computing and remote digital sub-station management.
