Enterprise Smart Protection & Control Devices
Explore our flagship OEM/ODM DIN-rail breakers, high-power smart sockets, and automation hardware engineered for international electrical standards.
The Paradigm Shift in Smart Electrical Distribution Systems
As commercial buildings, distributed photovoltaic arrays, and microgrid installations expand globally, traditional passive thermal-magnetic miniature circuit breakers (MCBs) no longer suffice. Corunsmart engineers intelligent DIN-rail MCB breakers that bridge heavy-duty electro-mechanical galvanic isolation with edge-computed IoT telemetry.
Simultaneous L+N Physical Disconnection
Unlike standard single-pole breakers that merely interrupt the live conductor, Corunsmart's advanced 1P+N, 2P, and 4P smart breakers integrate synchronized physical severance of both Line and Neutral conductors. This eliminates residual load-side neutral float voltage, safeguarding line maintenance technicians against reverse neutral surges and leakage faults in compliance with European IEC 60364 installation directives.
High-Precision Metrology Grade Chipsets
Equipped with specialized bidirectional active energy metering ICs, our breakers achieve dynamic Class 1.0 / Class 0.5 metering accuracy conforming to IEC 62053-21 standards. Real-time telemetry aggregates RMS voltage (V), RMS current (A), active power (W), reactive power (VAR), power factor (PF), and cumulative kilowatt-hours (kWh) across bi-directional grid export and import vectors.
Triple Protection Threshold Matrix
Combining traditional thermal bimetal overcurrent and magnetic short-circuit instant trip mechanisms (6kA/10kA breaking capacity) with solid-state software trip parameters. Procurement teams can configure granular over-voltage (240V–300V), under-voltage (140V–200V), over-current (1A–63A), and earth-leakage threshold actions (10mA–100mA) with programmable reset delay timers.
Global Enterprise Procurement Demands for Smart MCBs
B2B importers, government infrastructure contractors, and smart distribution panel builders require strict verification across mechanical, dielectric, and wireless criteria before factory qualification.
Icn Breaking Capacity
Industrial specifiers mandate standard IEC 60898-1 short-circuit breaking capability of 6,000A (6kA) and 10,000A (10kA). Corunsmart breaker chambers utilize heavy-gauge silver-graphite alloy contacts paired with 9-to-13-plate arc-chute de-ionizing fins to rapidly quench thermal arcs under 8 milliseconds.
Endurance & Motor Lifecycle
Automated opening and closing are driven by high-torque permanent-magnet miniature stepper motors or precision solenoids. Our smart MCBs sustain over 10,000 electrical cycles under full rated load (cosφ = 0.8) and over 20,000 mechanical switching operations, verified on automated continuous-load test benches.
Zero-Cross Switching Tech
Inrush currents from LED drivers, switched-mode power supplies, and inductive motor loads routinely weld relay contacts in inferior smart switches. Corunsmart incorporates microsecond zero-crossing phase detection firmware, triggering the circuit relay exactly at the AC sine wave zero-voltage crossover point.
Anti-Tamper & Padlock
Utility metering and sub-tenant rental distributions demand strict anti-tampering designs. Our DIN-rail housing structures feature physical safety padlock slide-latches that mechanically inhibit remote motorized reclosing when a field electrical technician locks the breaker out for maintenance.

Macro Commercial & Industrial Solutions
Corunsmart smart MCB devices deploy directly into distribution switchboards across diverse commercial verticals to optimize load balancing, predictive maintenance, and operational carbon accounting.
Multi-Tenant Commercial & Build-to-Rent (BTR)
Traditional utility sub-metering requires expensive wired RS-485 Modbus infrastructure and separate pulse counters. By installing Corunsmart Wi-Fi / Zigbee DIN-rail smart breakers inside each unit sub-panel, property managers obtain automated remote tenant billing data, programmable prepaid energy quotas, and instantaneous non-payment circuit de-energization via centralized cloud API dashboards.
Solar PV Generation & BESS Storage Balancing
Modern decentralized residential microgrids require bi-directional telemetry. Corunsmart 2P and 4P breakers calculate net grid export versus hybrid inverter import. When grid export tariffs plunge during midday peak solar yield, the breaker communicates via MQTT or local Matter bridges to divert surplus kilowatt-hours into heat pumps, thermal buffers, or battery energy storage systems (BESS).
EV Charging Fleet Dynamic Load Management (DLM)
Retrofitting high-output Level 2 electric vehicle chargers into commercial properties frequently risks overloading main service feeders. Corunsmart smart breakers communicate continuous line capacity back to local energy management controllers. When the cumulative facility demand approaches maximum contracted kVA thresholds, EV sub-circuits throttle automatically, preventing utility peak demand penalties.
Firmware Engineering: Tuya, Matter, Zigbee, & ESP32/Tasmota
Device agility defines project success. Unlike closed-ecosystem manufacturers, Corunsmart maintains multiple active wireless hardware stacks within identical form-factor DIN-rail housings.
Turnkey Tuya & Smart Life Cloud
Engineered for consumer brands and white-label retail channels requiring immediate out-of-the-box turnkey mobile apps, automated OTA firmware deployment, and native Amazon Alexa / Google Assistant skill certification. Provides automated energy visualization graphs, scheduled scene automations, and immediate push notifications for leakage or over-current trip occurrences.
Native Matter over Wi-Fi
The definitive standard for interoperable building systems. Corunsmart's Matter-certified smart breakers eliminate platform vendor lock-in. A single hardware SKU commissions seamlessly into Apple Home, Google Home, Samsung SmartThings, and Amazon Alexa ecosystems concurrently via localized IPv6 routing, guaranteeing local device response speeds even during wide-area internet outages.
ESP32, ESP32-C3 & Open Tasmota
For industrial systems integrators, university campuses, and privacy-conscious European utilities. We manufacture units flashed with open-source Tasmota or proprietary ESP-IDF firmware. Streams native JSON telemetry over secure TLS/MQTT to local Home Assistant installations, AWS IoT Greengrass, or Node-RED controllers without external cloud dependency.
Shenzhen Manufacturing Precision: Class 100 Cleanroom
Reliability in high-voltage circuit control requires contamination-free assembly. Shenzhen Corunsmart Co., Ltd. operates a 1,400 m² Class 100 dust-free purification workshop in Bao'an District, Shenzhen, deploying automated SMT and laser calibration.
Dual-Phase Factory Calibration
Every metrology-enabled breaker undergoes a two-stage active power calibration bench under pure resistive and inductive loads, adjusting offset gain in flash registers to ensure variance remains under ±1%.
Dielectric Voltage Withstand
100% of manufactured units are subjected to Hi-Pot dielectric impulse testing at 2,000V AC (50/60 Hz) for 60 seconds across open contact terminals, guaranteeing absolute insulation resistance against transient surges.
Thermal Accelerated Burn-In
Sub-assemblies run inside computer-monitored high-temperature aging chambers at 55°C ambient under continuous 100% rated load for 48 hours to eliminate early electronic component failure modes.
Flammability UL94-V0 Resin
Breaker housings utilize precision-molded halogen-free flame-retardant polyamide (PA66) reinforced with glass fiber, reaching UL94-V0 compliance with glow wire ignition resistance up to 960°C.
The Future of Solid-State & AI-Driven Arc Fault Interruption
The low-voltage power sector is transitioning from mechanical contactors toward solid-state semiconductor circuit protection. Corunsmart's R&D engineering lab in Shenzhen is actively advancing next-generation topologies.
2025: Native Matter 1.3 Energy Profiling

2026: Edge AI Arc Fault Detection (AFDD)
Embedding tinyML neural network inference onto low-power RISC-V edge silicon to analyze high-frequency current wave distortion signatures in real time, detecting dangerous micro-arcing faults before electrical fire ignition occurs.
2027: GaN / SiC Solid-State Breakers (SSPC)
Transitioning from mechanical contact plates to Gallium Nitride (GaN) and Silicon Carbide (SiC) semiconductors, achieving complete fault current interruption within microseconds—over 1,000 times faster than mechanical trip solenoids.
2028-2030: Autonomous Sub-Panel Load Shedding
Decentralized peer-to-peer mesh negotiation across multiple breakers within a single panel. In the event of main utility supply curtailment, smart breakers autonomously negotiate critical versus non-critical shedding hierarchies without requiring internet connectivity.
