Discover high-capacity, thermally adjustable, and heavy-duty switchgear units custom-machined for critical power grids.
As the global power sector undergoes a paradigm shift toward sustainability, decentralized grids, and electric vehicle infrastructures, safety switches such as Molded Case Circuit Breakers (MCCB) have emerged as indispensable assets. Specifically, the 160A MCCB (Molded Case Circuit Breaker with a 160-ampere frame size) serves as a critical terminal node and secondary distribution guard. It bridges the gap between massive main distribution switchboards (often regulated by high-capacity Air Circuit Breakers) and localized branch circuits.
Globally, manufacturers are facing stricter regulatory standards like IEC 60947-2, UL 489, and regional codes aiming to limit carbon footprints while maximizing short-circuit breaking capabilities (Icu). Industrial hubs in Europe, the Americas, and APAC are aggressively retrofitting their legacy switchboards with advanced MCCB solutions to avoid catastrophic downtime and mitigate arc-flash hazards. A premium 160A MCCB from an experienced Chinese manufacturer provides global businesses with a cost-effective, durable, and highly adaptive solution that complies with these rigorous requirements.
Founded in 2015, Acereare Electric operates with two wholly-owned subsidiaries: "RuiRui Electric" and "KeRui Electric". Building on over 20 years of craftsmanship inherited across two generations, the current proprietor registered the company to scale operations internationally. Today, our factory is recognized as a premier original manufacturer (ODM/OEM) in China, ranking at the top tier of comprehensive experience and technological capability in low-voltage circuit breakers.
We are a professional original manufacturer integrating R&D, production, and sales. We specialize in Molded Case Circuit Breakers (MCCB), Air Circuit Breakers (ACB), and premium copper/iron stamping components. We have established strategic cooperation relationships with nearly 100 high-end partners worldwide.
Understanding the internal dynamics of a molded case circuit breaker is critical for selecting the right safety gear for industrial frameworks. A 160A rated breaker must dissipate high thermal energies during overloads while clearing short circuits within milliseconds. Our engineering focuses on three core pillars:
Featuring adjustable thermal-magnetic mechanisms and electronic LSIG options. Engineers can fine-tune thermal overload settings (0.8 to 1.0 × In) and electromagnetic instant tripping parameters to match the load characteristics of the protected equipment.
Our moving contacts incorporate advanced silver alloy plating. This metallurgical design significantly lowers contact resistance, minimizes thermal losses at full load, and resists contact welding under high-current faults.
Engineered to deliver breaking capacities up to 200kA at 400V/690V. The rapid-arc extinguishing chamber utilizes dynamic steel grid splitters to cool and collapse arc currents in fractions of a cycle, ensuring maximum safety.
Acereare manufactures the internal metal stamping components in-house. This vertical integration guarantees dimensional accuracy, robust mechanical life (up to 20,000 operations), and consistent trip curve reliability across our entire product line, including the ARM1, ARXM3, and ARM3E series.
Acereare MCCBs are engineered to maintain operational integrity in demanding conditions worldwide, from marine ports to high-altitude installations.
Constructed with specialized low-temperature resistant polymers and low-viscosity lubricants. Standard parts undergo thickened plating treatments, and units are backed by certified low-temperature test reports at -40 ℃.
Designed to withstand damp, saline marine air. Our machines undergo 72-hour salt spray testing (48 hours for sub-assemblies), making them suitable for docks, ships, and offshore power configurations to prevent corrosion and tracking faults.
At high altitudes, thin air decreases dielectric properties and thermal dissipation. Our engineering team provides high-altitude derating tables and adjusted coefficients to guarantee safe operation above 2,000 meters.
Optimized for sub-distribution panels in large residential buildings, commercial towers, and smart homes. These MCCBs protect appliance circuits against overload and short-circuit damage with high flexibility and operational safety.
Manufactured with high-temperature resistant plastics. The controller surface is finished with thermal insulation, and copper components feature corrosion resistance. Tested in our constant temperature lab at 55 ℃.
Supports smart grid architectures with digital metering, communication protocols, edge computing, and remote control. This allows operators to run telemetry (sensing, adjusting, control, signaling) for automated energy management.
We offer comprehensive support from design and compliance to packaging and logistics, serving as your trusted overseas manufacturing facility.
Increase brand visibility with custom logo laser engraving and tailored packaging. Our team uses premium raw materials to help you build local authority, and offers rapid sample customization to speed up product launches.
Gain access to professional mold design, functional development, and international testing reports (with refundable options based on order volume). We guarantee a 24-hour response time to support your operations.
Utilize customized trademark catalog designs, packaging configuration (inner/outer boxes), and tailored logos. We support small-batch order trials to help you test local markets with minimal initial overhead.

We utilize modern testing equipment and advanced software management to ensure every circuit breaker complies with international standards.
Our production facilities utilize modern processing techniques, precision equipment, and testing instruments across more than 10 manual and automated assembly lines. Our R&D department features over 50 engineers with 5+ years of industry experience, specializing in 3D structural parts, tooling, and finished product design, completing over 50 projects annually.
Acereare manages two factories dedicated to components and complete machines, linking operations through integrated ERP, MES, and PLM software. Our quality team uses over 150 testing instruments and employs 20+ inspectors to ensure strict multi-step testing throughout the production cycle.
As industrial distribution systems move toward smart grid integration, our R&D efforts are focused on three core technical goals:
By investing in these smart features, Acereare helps power engineers build reliable, efficient distribution systems prepared for future electrical demands.
Technical answers to help engineers and procurement teams select and configure 160A Molded Case Circuit Breakers.
Thermal-magnetic trip units use a bimetal strip for overload protection and an electromagnet for short-circuit protection. They are cost-effective and reliable. Electronic trip units use microprocessors to monitor current waveforms, offering more precise and adjustable trip curves (LSIG - Long, Short, Instantaneous, Ground fault settings) to support complex selectivity coordination.
For installations above 2000m, the thinner air reduces cooling efficiency and dielectric strength. Standard derating factors apply: at 3000m, the rated current is typically derated to 0.96 × In, and the rated operating voltage is derated to approximately 0.88 × Ue. Contact our engineering team for complete derating tables based on your specific application.
We provide a range of breaking capacities, including standard (35kA to 50kA), high-capacity (65kA to 85kA), and specialized industrial options up to 200kA at 400V/690V. This ensures reliable protection across varying fault levels in different distribution networks.
Silvering moving contacts lowers contact resistance, reducing temperature rise at the terminals during full-load operation. The high conductivity of the silver alloy also prevents contact pitting and welding under short-circuit conditions, extending the electrical service life of the breaker.
Yes. We offer both front plug-in and back plug-in layouts for easy installation and maintenance. These configurations allow swift replacement of breakers without disturbing the main busbar connections, reducing downtime in critical systems.
