Flagship Smart Switching & Energy Control Units
Factory-direct smart switches, DIN-rail modules, and telemetry nodes engineered for turnkey OEM/ODM customization across international power grids.
The Smart Breaker Revolution: Microgrids, Matter 1.3 & Edge-AI Telemetry
The global electrical protection market is shifting decisively from passive mechanical Miniature Circuit Breakers (MCBs) to intelligent, software-defined DIN-rail telemetry nodes. As distributed energy resources (DERs) surge, original equipment manufacturers must navigate rapid convergence between traditional electromechanical safety and embedded edge computing.
Bi-Directional Metering for Solar & ESS
Modern residential and commercial sub-panels require real-time tracking of both forward grid draw and reverse solar injection. Next-generation ODM smart breakers feature dual-channel Class 1.0 energy measurement chips capable of computing net metering, reactive power, and harmonic distortion directly on the DIN rail.
Matter 1.3 / 1.4 Energy Management
Closed proprietary ecosystems are giving way to the Connectivity Standards Alliance (CSA) Matter specification. Corunsmart's advanced ODM platforms integrate Matter over Wi-Fi and Thread, facilitating unified native telemetry reporting to Apple HomeKit, Google Home, Amazon Alexa, and Home Assistant without cloud vendor lock-in.
Solid-State & Arc-Fault Edge Diagnostics
Moving beyond simple bimetallic thermal strips, Corunsmart embeds high-speed microcontrollers running real-time wave sampling algorithms. This enables sub-cycle microsecond trip speeds for short circuits and advanced Edge-AI Fourier transform analysis to identify dangerous series and parallel arcing (AFDD/AFCI).

Macro Industry Solutions: From Smart Homes to Resilient Microgrids
Corunsmart engineers tailored hardware configurations and customized firmware routines for demanding vertical applications across residential, commercial, and off-grid scenarios.
1. Solar Photovoltaic & BESS Arbitrage
Integrated DIN-rail smart breakers measure power flow directions dynamically. When rooftop PV generation peaks and grid export feed-in tariffs are suppressed, the breaker's automated logic signals EV chargers, water heaters, and battery storage systems to initiate charging, maximizing self-consumption and return on investment.
2. Multi-Tenant Real Estate & Sub-Metering
For apartment complexes, student housing, and commercial plazas, Corunsmart offers multi-tariff smart energy meters with remote pre-paid disconnection capabilities. Property managers can automate kWh billing via MQTT APIs or cloud dashboards without deploying expensive third-party manual meter-reading crews.
3. EV Fleet & Smart Charging Stations
Electric vehicle chargers can easily overload main building panels during simultaneous plug-in events. Our smart breakers dynamically communicate with energy management systems (EMS) via local Zigbee mesh or Wi-Fi to throttle load currents or stagger charging schedules, avoiding expensive utility peak demand penalties.
4. Smart Hospitality & Hotel Management
Eliminate obsolete plastic master keycards. Intelligent sub-panel breakers integrate directly with Property Management Systems (PMS). When guests check in, HVAC and lighting circuits activate automatically; upon checkout, high-power circuits power down, slashing commercial electricity waste by up to 34%.
5. Cold-Chain & Critical Infrastructure
Supermarket refrigeration and pharmaceutical storage require immediate alerts prior to breaker trips. Corunsmart breakers report real-time temperature, leakage current rise, and phase imbalances. Preventative alerts allow facility managers to replace degraded compressors before total system failure.
6. Smart Agriculture & Irrigation Pumping
Coupled with our smart soil moisture and solar sensors, Corunsmart high-amperage breakers manage remote 3-phase pump stations. Farmers schedule automated deep-well irrigation based on hyper-local ground metrics and off-peak electricity tariffs, drastically cutting water and operating costs.
Global Electrical Codes, Certifications & Regional Engineering
Navigating regional safety and electrical standards is the primary barrier for smart breaker commercialization. Corunsmart provides end-to-end certification documentation, lab-tested report packages, and bespoke physical adaptations for every major global market.
European Union (CE, RoHS, EN 60898-1)
Full compliance with CE Low Voltage Directive (LVD 2014/35/EU) and Radio Equipment Directive (RED 2014/53/EU). Our models feature genuine 35mm DIN-rail clips, dual-terminal cage clamps for flexible wiring, and optional simultaneous Live + Neutral (L+N) double-break disconnects ensuring zero voltage on the load side during maintenance.
North America (UL 489, UL 1053, FCC)
Engineered to fulfill strict UL 489 branch protection standards, including 10kA short-circuit interrupt capacity, dielectric voltage withstand, and 120V/240V split-phase compatibility. Built-in FCC Part 15 Class B certified radio modules eliminate interference with commercial communication equipment.
Latin America, UK & APAC (INMETRO, UKCA)
Tailored engineering variants developed specifically for Brazil (INMETRO standard backboxes and 127V/220V grid volatility), UKCA conformity for British infrastructure, and high-humidity tropicalized PCB conformal coatings designed for reliable deployment across Southeast Asian and Mexican environments.
The Future: Solid-State Digital Breakers & AI-Driven Arc Interruption
Corunsmart's advanced research team in Shenzhen is pioneering the convergence of wide-bandgap semiconductors (Silicon Carbide - SiC and Gallium Nitride - GaN) with DIN-rail circuit protection architecture.
Sub-Microsecond Trip Times
While mechanical spring-loaded contacts take between 5 to 15 milliseconds to separate and extinguish electric arcs, solid-state SiC breakers disconnect overcurrent paths in under 1 microsecond, effectively eliminating electrical fire sparks and contact degradation.
Zero-Crossing Soft Switching
Microcontroller-driven solid-state gates trigger switching precisely at the AC voltage zero-crossing point. This virtually eliminates high-voltage inductive kickback spikes, drastically extending the service life of connected motors, LED drivers, and industrial loads.
Edge TinyML Waveform Analysis
By embedding low-power neural processing cores (NPU) inside the DIN enclosure, future smart breakers will differentiate between harmless benign motor-starting noise and lethal micro-arcing inside wall framing, avoiding nuisance tripping while maximizing fire safety.
Open Firmware Ecosystems
Corunsmart continues to champion open developer ecosystems. Our hardware supports custom ESP-IDF routines, Tasmota open-source builds, ESPHome, and direct local MQTT broker connections, granting enterprise integrators 100% data sovereignty and cloud independence.
