High-precision structural parts and contact components designed to meet strict IEC 60947-2 switchgear standards for Italian OEMs.
Italy stands as Europe's second-largest manufacturing base, heavily reliant on highly advanced automation, smart grids, and renewable energy sectors centered in industrial hubs like Lombardy, Veneto, and Emilia-Romagna. The accelerated transition toward green electrification (PV solar plants, EV charging grids, and industrial energy storage systems) has driven high-quality demands for electrical switchgear components. In Milan, Turin, and Bologna, manufacturers require high-conductivity, fatigue-resistant Molded Case Circuit Breaker (MCCB) welding parts and contact terminals that meet rigorous CE and IMQ safety frameworks.
At Acereare Electric, we address this exact demand. Our engineering team designs and manufactures metal stamping connection plates, silver-plated copper moving contacts, and bimetallic brazed components that guarantee structural integrity under continuous thermal loading. By integrating advanced Chinese precision toolmaking with European mechanical standards, we deliver the custom solutions Italian OEMs need to maintain global competitiveness.
Our MCCB metal parts conform perfectly to regional power requirements:
Acereare Electric, registered officially in 2015, represents the integration of two wholly-owned production subsidiaries: "RuiRui Electric" and "KeRui Electric". Our operational heritage extends back over 20 years, carrying over two generations of technical mastery in precision metal stamping, resistance brazing, and molded case circuit breaker architecture. Today, we rank as one of the top ODM/OEM partners in China for switchgear parts, serving over 100 high-end electrical engineering clients worldwide.
Underneath the housing of a high-performance MCCB sits a complex array of copper stampings and silver contact tips welded to sub-millimeter tolerances.
We operate multi-station progressive die press lines that stamp moving and fixed contacts with tolerances kept strictly under ±0.01 mm. This high dimensional consistency prevents arcing across contact interfaces.
Using resistance projection welding and high-frequency induction brazing, we achieve structural bonds between the silver contact alloy (AgSnO2, AgNi) and red copper (C1100 / C1020). High shear strength prevents contacts from detaching during heavy tripping loads.
Electroplated silvering thicknesses are monitored via X-ray fluorescence (XRF) to maintain a consistent layer from 3 to 15 microns. This protective plating lowers contact resistance, reducing localized heat generation inside switchboards.
| Substrate / Backing Material | Contact Tip Composition | Shear Strength Rating | Primary Application Fields |
|---|---|---|---|
| ETP Copper (C1100) | AgSnO2 (90/10) | ≥ 120 MPa | Standard Industrial Circuit Protection (250A - 630A) |
| Oxygen-Free Copper (C1020) | AgNi10 / AgNi20 | ≥ 140 MPa | Heavy Duty Machine Automation & Dynamic Relays |
| Copper-Zirconium Alloy (CuZr) | AgWC (Silver Tungsten Carbide) | ≥ 165 MPa | High-Voltage Photovoltaic Solar DC Breakers (1000V - 1500V) |
We combine end-to-end tooling design, advanced enterprise resource planning (ERP), and strict quality control to streamline procurement for European OEMs.
We run six distinct metal processing operations under one roof, backed by ten automated and manual assembly lines to assure fast throughput.
Over 50 dedicated R&D engineers develop custom tools, dies, and 3D modeling drafts, completing over 50 product development designs annually.
Our dual factories manage production schedules via ERP and U8 software, ensuring components arrive on time at Italian hubs like Genoa and Trieste.
150+ testing instruments and 20+ QC inspectors verify parts through MES and PLM software to ensure zero-defect outgoing batches.
Italian switchboards operate in diverse conditions, from cold Alpine peaks to marine environments and high-temperature manufacturing plants. Our MCCBs are built to withstand them all.
Our contacts use low-temperature grease and specially passivated alloys to prevent structural brittleness. We provide -40°C testing reports for switchgear installed in high-altitude environments.
We perform 72-hour salt spray testing on complete assemblies and 48-hour testing on sub-assemblies, providing corrosion protection for seaside installations and marine switchgear.
For installations above 2,000 meters, we adjust clearance distances and insulation design to match high-altitude derating coefficients, preventing air insulation breakdown.
Our residential-grade MCCB components deliver low contact resistance and high mechanical durability, safeguarding household appliances from overloads and short circuits.
Thermal stability tests are conducted in our 55°C constant-temperature testing rooms. We use high-grade insulation layers and corrosion-resistant copper parts to prevent thermal runaway.
We manufacture custom copper components integrated with current transformer (CT) shunts, enabling micro-measurement, remote edge computing, and real-time power monitoring.
From tool design to packaging, we support customized brand development for European industrial distributors.
Enhance market presence with custom laser-etched logos, premium raw materials, rapid sample creation, and unique structural layouts designed to differentiate your brand.
We provide full-service manufacturing, including custom mold design, functional engineering, international certification testing support, and round-the-clock technical communication.
We offer customized packaging design, specialized catalogs, small-batch manufacturing, and tailored testing reports to meet the requirements of regional distributors.
Quality reliability is critical for circuit breakers. Inside our laboratory, we inspect incoming copper sheets and outgoing assemblies to verify dimensional accuracy, plating thickness, and contact alignment.
We test mechanical endurance, temperature rise under load, and short-circuit response. By managing production through PLM, BI, ERP, and MES software, every batch remains fully traceable from raw copper to finished parts.
