Grid Decarbonization & Sub-Metering

Global regulatory mandates (such as the EU Energy Efficiency Directive and US Title 24) demand revenue-grade bi-directional sub-metering inside the primary panelboard. Custom breaker factories are embedding Class 1.0 metering ICs to calculate Active, Reactive, and Apparent power, capturing micro-generation data from solar PV inverter inputs and EV charging spikes.

Predictive Arc & Thermal Fault Sensing

Traditional breakers only react when fire-risk thresholds are exceeded. Modern OEM configurations integrate thermistors directly on the internal contactor armatures alongside DSP-driven high-frequency sampling to recognize series and parallel arcing signatures (AFDD) before insulation degradation culminates in catastrophic flashover.

Simultaneous Live & Neutral Cut-Off

Standard low-cost single-pole breakers only sever the line phase, leaving floating neutrals that pose deadly risks during multi-tenant neutral faults or solar back-feeds. Corunsmart’s flagship L+N Double Cut Breakers guarantee complete galvanic isolation on trips, meeting stringent VDE and AS/NZS electrical safety codes.

Macro-Sector Implementations: Real-World Deployments

Custom circuit breaker modules engineered for diverse operating ambient conditions, network topologies, and industrial duty cycles.

Multi-Tenant Hospitality & Residential Buildings

Eliminate manual meter-reading labor with DIN-rail WiFi/Zigbee circuit breakers featuring automated prepay metering, remote overload shedding, and tenant checkout disconnects via centralized building management systems (BMS).

Telecom Base Stations & Edge Computing Shelters

Unattended telecom towers require auto-reclosing circuit breakers. In the event of transient lighting-induced nuisance trips, our DSP-monitored breakers test loop impedance and perform safe automatic reclosing without requiring technician dispatch.

Solar Inverter Balancing & Commercial EVSE

Three-phase 3P+N motorized smart breakers enable real-time dynamic load balancing across EV fleets and microgrids, capping building envelope peak-demand charges through automated MQTT control pulses synchronized with electricity price tariffs.

Factory Footprint

Procurement Due Diligence

Frequently Answered Technical & Supply Inquiries

Real inquiries resolved for global electrical wholesalers, engineering EPCs, and IoT system integrators.

How does your factory solve neutral line floating hazards?

Our smart breakers feature mechanical double-pole ganged linkage. Unlike cheap alternatives that switch only the live line, our units trigger a simultaneous physical break across both Line and Neutral channels, removing residual voltage on downstream circuits during trip incidents.

Can you provide pure open-source Tasmota / MQTT firmware out of the box?

Yes. In addition to commercial Tuya and Tuya-Matter platforms, we run specialized SMT lines flashing open-source firmware on ESP32, ESP32-C2, and ESP32-C3 modules. This enables local polling over MQTT for Home Assistant without any internet dependency.

What is the standard lead time for customized injection molds and tooling?

Tooling for custom faceplates or proprietary DIN housings takes 28 to 35 days. Standard hardware casing variants with custom silk-screen branding and custom firmware are dispatched in 10 to 14 days under our fast-track OEM program.

What certifications apply when importing to the USA, EU, or UK?

Our products and production processes hold certified ISO 9001:2015, BSCI, CE (LVD/EMC), RoHS, UKCA, FCC, and ETL/UL compliance reports. Specific test lab reports are released along with our technical data packages upon order inquiry.
