In the realm of electrical engineering, the 16 Amp Miniature Circuit Breaker (MCB) serves as the backbone of circuit protection. As a global manufacturer, Zhejiang Shuorui Electric Co., Ltd. analyzes the critical role of these devices in an era defined by renewable energy integration and smart building automation.
Our 16 Amp MCBs utilize advanced thermal-magnetic tripping mechanisms to provide dual protection: thermal protection against sustained overloads and electromagnetic protection against sudden short circuits. This ensures the longevity of connected appliances and terminal equipment.
Engineered for high-demand environments, our circuit breakers offer breaking capacities ranging from 6kA to 10kA, adhering to IEC 60898-1 and IEC 60947-2 international standards. This allows for safe disconnection under extreme fault conditions.
We provide specialized trip curves for different loads: Type B for domestic lighting, Type C for standard commercial loads, and Type D for high-inductive industrial motors. This customization eliminates nuisance tripping while maintaining maximum safety.
Located in Liushi, Wenzhou—the "Electrical Capital of China"—Zhejiang Shuorui Electric Co., Ltd. leverages a world-class supply chain ecosystem. Our proximity to high-grade raw material suppliers (pure copper contacts, flame-retardant polymers) allows us to offer wholesale circuit breakers that balance cost-efficiency with premium quality.

The rise of Smart Grids necessitates MCBs with remote monitoring capabilities. Our WiFi Intelligent Reclosing Protectors represent the next generation of 16A protection, allowing real-time current monitoring and remote shut-off via mobile applications.
With the surge in Photovoltaic (PV) installations, DC circuit breakers (up to 1500VDC) have become vital. As a leading MCB manufacturer, we are optimizing arc-extinguishing chambers to handle the unique challenges of DC electrical arcs.
Global regulations are shifting towards eco-friendly electrical components. Shuorui Electric uses halogen-free plastics and silver-alloy contacts that are compliant with RoHS and REACH standards, ensuring a lower carbon footprint for global projects.
16A MCBs are the standard for socket outlets and small power circuits in Europe, Australia, and Asia. Our products provide reliable protection for HVAC systems, kitchen appliances, and home EV chargers.
For data centers and shopping malls, we provide MCBs with auxiliary contacts (OF) and shunt releases (MX) to integrate with building management systems for automatic fire shut-offs and fault signaling.
Our specialized PV DC circuit breakers and Surge Protective Devices (SPD) are critical for protecting solar inverters and battery storage systems against lightning strikes and voltage spikes.
For global wholesalers and EPC contractors, reliability is non-negotiable. Zhejiang Shuorui Electric Co., Ltd. embodies the E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) principles required for critical electrical infrastructure.
Strict inspection from raw material entry to 10-point final testing, including tripping speed and temperature rise tests.
From MCB, MCCB to SPD and Photovoltaic connectors, we provide a "One-Stop Shop" solution for all distribution needs.
Proven track record of manufacturing for world-renowned electrical brands, adhering to their rigorous internal quality audits.
Products carry CE, TUV, and CCC certifications, ensuring smooth customs clearance and local regulatory compliance.
A: The 16A rating (In) is the nominal rated current. The breaker can continuously carry 16 Amperes of current without tripping under standard ambient temperatures (usually 30°C). If the current exceeds this value, the thermal mechanism will trigger based on the time-current curve.
A: It is highly discouraged. DC arcs are much harder to extinguish than AC arcs. AC breakers lack the permanent magnets and specialized arc chutes required to safely quench a DC arc. For PV systems, you should use our dedicated DC MCB series (e.g., 500VDC or 1000VDC).
A: Breaking capacity (Icn) is the maximum fault current the MCB can successfully interrupt without permanent damage. 6kA is standard for residential use, while 10kA is often required for commercial or industrial applications near a transformer where prospective short-circuit currents are higher.
A: We use high-grade silver-graphite alloy contacts which offer excellent conductivity and resistance to welding during short circuits. Additionally, our housings are made from high-strength, flame-retardant VO grade nylon.
A: Yes, as a manufacturer, we can calibrate our assembly lines for specific tripping sensitivities (B, C, or D curves) and even offer specialized non-standard ratings to meet specific regional utility requirements.
