ODM Mini Smart Breaker Manufacturer & Factories

Smart breakers manufactured by Corunsmart implement a strictly bifurcated safety topology. The primary short-circuit and overcurrent protection relies on independent, mechanical thermal-magnetic trip bimetals and electromagnetic solenoids certified to standard breaker safety norms. The edge MCU, relay driving circuitry, and wireless radios operate strictly as a secondary control layer. In the event of firmware crash, network disconnect, or complete digital processor failure, the mechanical tripping mechanism will trip independently within standard millisecond safety curves without software intervention.

Yes. We provide complete firmware flashing and automated MAC/UUID serialization directly on our SMT production lines. For open-ecosystem and commercial IoT brands, we build hardware utilizing Espressif ESP32-C2, ESP32-C3, or ESP32-S3 modules, pre-loaded with client-provided custom builds, open-source Tasmota, ESPHome, or custom enterprise MQTT code that connects straight to private AWS IoT Core, Azure IoT, or local Home Assistant servers without Tuya cloud dependence.

Our motorized actuators are engineered with hardened planetary gearboxes and silver-alloy contact tips. Under full rated current (up to 63A continuous resistive load at 230V/400V), our smart circuit breakers achieve over 10,000 electrical remote on/off cycles and over 20,000 manual mechanical operations, easily surpassing the baseline performance requirements of IEC 60898-1 and IEC 60947-2 standards.

Each breaker contains an integrated dedicated energy metering IC paired with high-stability micro-current transformers and low-noise voltage dividers. During our automated end-of-line testing (EOLT), specialized digital calibrators inject precision reference voltages and currents across 5 power points. The calibration coefficients are computed automatically and burned into the device's non-volatile memory, ensuring Class 1.0 (±1%) or optional Class 0.5 revenue-grade measurement precision across the entire operating temperature envelope (-25°C to +60°C).

Standard private-labeling (custom packaging, silk-screen logos, custom default firmware settings) starts at an MOQ of 500 to 1,000 units with typical lead times of 2 to 3 weeks. Full ODM projects involving new plastic tooling enclosures, custom PCB form factors, or specialized terminal geometries require an initial design & prototype window of 25 to 30 days, followed by 35 days for pilot production, with volume MOQs starting at 5,000 units.
