Flagship Smart Breakers & Dynamic Switchgear
Verified DIN-rail and smart module configurations engineered for immediate OEM white-label deployment and architectural integration.
Shenzhen Supply Chain Agility Meets Rigid Engineering Disciplines
As a seasoned tier-one smart miniature circuit breaker (Smart MCB) manufacturer operating out of Shenzhen's Bao'an industrial hardware cluster since 2014, Shenzhen Corunsmart Co., Ltd. eliminates the typical supply chain bottlenecks faced by global energy brands. We maintain an end-to-end ecosystem integrating high-precision mold fabrication, SMT automated component placing, mechanical assembly, and multi-stage testing in our certified Class 100 dust-free facility.
By leveraging an agile component sourcing network across the Pearl River Delta, our lead times for custom tooling and protocol engineering remain unmatched. Our dual-track inventory safeguards strategic microcontrollers—including ESP32 series, Realtek, and Telink wireless silicon—protecting B2B integrators against global semiconductor volatility.

Global Industrial Landscape: The Smart Switchgear Revolution
Traditional thermal-magnetic circuit breakers are rapidly giving way to edge-computing micro-switchgear. Discover how industry verticals are modernizing grid edges.
Grid Edge Decarbonization
With regulatory pressures such as the EU Energy Performance of Buildings Directive (EPBD) and ASHRAE Standard 90.1, commercial structures require sub-circuit energy visibility. Smart MCBs provide sub-metering without external CT installation.
Distributed Renewable Balancing
Residential microgeneration, rooftop solar arrays, and bidirectional battery storage demand fast bi-directional energy monitoring and autonomous trip controls to manage phase imbalances and anti-islanding constraints.
Predictive Maintenance & Safety
By capturing arc signatures, thermal degradation patterns, and microscopic earth leakage current variations in real time, edge-enabled Smart MCBs preempt electrical fire hazards long before catastrophic structural damage occurs.
Engineered for High-Stakes Field Deployments
Our OEM Smart MCBs and complementary controls operate seamlessly across demanding infrastructure topologies around the world.
EV Charger Sub-Panels
Dynamic load shedding at 63A prevents main service drops from overloading during simultaneous Level 2 charging and heat pump operations.
Multi-Tenant Metering
Accurate revenue-grade sub-metering with integrated neutral-line disconnect enables landlords to isolate tenant power remotely upon lease expiration.
Telecom Cell Towers
Autonomous circuit self-healing and remote reset capabilities eliminate costly truck rolls to remote auxiliary telecom equipment shelters.
Commercial Cold Chain
Real-time current and temperature anomaly detection alerts operators to compressor stall conditions before refrigeration temperature breaches occur.
Silicon-to-Cloud Engineering Flexibility
Bridge closed proprietary apps and open source building management networks with our modular microcontroller architectures.
Matter-Native & Open Firmware Stacks
Modern system integrators cannot afford single-vendor lock-in. Corunsmart addresses this through hardware-software decoupling. Our smart circuit breaker lines can ship with turnkey Tuya Smart or Tuya-Matter firmware for immediate retail out-of-the-box readiness across Apple Home, Google Home, Amazon Alexa, and Samsung SmartThings.
Alternatively, for industrial controls, enterprise SCADA, and private Home Assistant rollouts, we flash our ESP32-C2 and ESP32-C3 hardware with Tasmota or proprietary MQTT-centric firmware. This allows completely local, zero-cloud execution, keeping critical electrical controls safe from external network interruptions.
