High-Performance, Smart MCCB & ACB Systems Tailored for Ireland's Fast-Growing Industrial Grid and Data Center Infrastructure
Send Inquiry NowAdvanced molded case circuit breakers (MCCB) built to satisfy Ireland's demanding technical conditions.
Ireland's energy infrastructure is undergoing a massive transformation. With EirGrid driving the Deliving a Secure Sustainable Electricity System (DS3) programme, the grid is adjusting to manage up to 75% non-synchronous renewable energy penetration, primarily wind power. This creates unique challenges for electric distribution manufacturers, who must supply high-reliability switchgear to support grid stability.
Furthermore, Ireland has become the premier data center hub in Europe. High-density server facilities in the Dublin region demand robust, redundant, and highly secure low-voltage distribution configurations. Molded Case Circuit Breakers (MCCB) and Air Circuit Breakers (ACB) must exhibit absolute selective coordination to guarantee zero-downtime operations, even under extreme system faults.
Globally, the expansion of microgrids, battery energy storage systems (BESS), and electric vehicle fleet charging hubs demands switchgear that can withstand higher DC voltages and bidirectional current flows. Modern power protection is shifting from static mechanical breakers to digital, intelligent distribution devices equipped with real-time metering, edge computing capacity, and remote communication buses (Modbus-RTU, Profibus, Ethernet).
Acereare Electric (incorporating RuiRui and KeRui manufacturing divisions) solves these global and local challenges through vertical integration. With more than 20 years of craftsmanship, our factories manage everything from tool stamping, silver contact fabrication, and electronic trip unit assembly to automated validation testing. This internal control guarantees cost efficiency, custom design flexibility, and short supply times for global buyers.

Automated Production Lines
Providing custom, high-reliability circuit breakers backed by deep industrial expertise.
One-stop processing with high-precision fabrication. Our factories deploy 6 specialized processing methods, maintaining robust output metrics across 10 manual and automated assembly lines.
50+ experienced R&D engineers skilled in complex 3D tool modeling, part simulation, and electronic logic development, delivering 50+ fresh designs yearly to meet evolving grid requirements.
We manage two dedicated production sites powered by ERP and U8 management software. We coordinate processing stages from raw steel and copper input to final tested breakers.
Integrated PLM, MES, and BI software platforms regulate checking operations across our internal labs, deploying 150+ specialized test instruments and 20+ QC inspectors.
Acereare breakers are designed to operate reliably in demanding industrial conditions.
Our units use low-temperature rated lubricants and specialized casing compounds, verified to operate at down to -40°C. Perfect for Irish upland wind generation plants and exposed trackside power installations.
Tested for up to 72 hours under dense salt fog conditions. Essential for coastal wind arrays, Irish port infrastructure (Port of Cork, Dublin Port), and offshore marine distribution setups.
Designed to account for thin-air thermal derating. We supply calibrated thermal maps for deployments exceeding 2000m altitude to guarantee reliable trip characteristics.
Engineered to protect critical infrastructure against overloads and short circuits, our compact switchboard solutions provide high breaking capacity for commercial and residential buildings.
Tested inside our 55°C environmental chambers. We use insulated controller surfaces and moisture-resistant copper pathways to prevent nuisance trips in warm industrial settings.
Supports Modbus communication, real-time energy metering, and edge fault analysis. Provides critical data monitoring for smart factories and modern industrial facilities.
How we help global OEMs and Irish switchgear builders maintain a competitive edge.
Build your brand's market share with customized logos, custom outer/inner packaging design, and bespoke user manuals. Our fast prototyping service helps you introduce new products to the Irish market quickly.
We offer full mold modification, customized operational functions, and global certification testing support (CE, CB, SEMKO, VDE). All engineering is backed by our 24-hour rapid-response technical team.
Collaborate directly with our engineering team to design custom circuit breakers. We offer custom stamping tools, electronic trip unit logic modifications, and flexible minimum order quantities (MOQs).

Find answers to common questions about our circuit breakers and engineering capabilities.
Yes. All our circuit breakers are designed, manufactured, and tested to meet IEC/EN 60947-1 and IEC/EN 60947-2 standards. We provide full international test certifications (including CE and CB) to ensure seamless integration into European and Irish electrical installations.
For data center switchboards, we recommend our smart MCCB series (such as the ARM6Z) which feature built-in LSIG trip units and remote communication capabilities. These units provide precise selective coordination, enabling localized fault containment and minimizing downtime in mission-critical server facilities.
We manufacture key internal components in-house, including silvered contacts and metal stamping parts. This allows us to control material quality, thickness, and tolerances, ensuring consistent electrical contact pressure and low resistance over the breaker's operating life.
Leveraging our integrated ERP system, standard custom OEM production runs are typically completed within 3 to 4 weeks. Shipping to ports like Dublin or Cork generally takes an additional 4 to 5 weeks by ocean freight, or 1 to 2 weeks via rail/air transport hubs.
