Precision-engineered components for modern electrical infrastructure
In the rapidly evolving landscape of global industrial electrification, the GNM1EL Series Residual Current Operated Circuit Breaker (RCCB/RCBO) represents the pinnacle of safety engineering. As a leading China GNM1EL series manufacturer, Zhejiang Igoye Energy Technology Co., Ltd. integrates sophisticated electronic sensing with robust mechanical interruption to mitigate the risks of electric shock and equipment-damaging leakage currents.
Utilizing high-permeability magnetic cores to detect zero-sequence current imbalances as low as 30mA, providing instantaneous protection for human life and sensitive electronics.
Available in various pole configurations to suit single-phase residential applications and complex three-phase industrial power grids.
Optimized internal resistance significantly reduces heat dissipation during continuous operation, extending the service life of the switchgear cabinet.
Located in the heart of the Yueqing Economic Development Zone, Zhejiang Province, our facility is strategically positioned near major logistics hubs like Qili Harbor and Yueqing Bay. With over 12,000 square meters of standardized workshop space, we have committed ourselves to the R&D and production of premium low-voltage electrical appliances.
Our philosophy of "customer-centered, seeking development for employees, and contributing to society" drives us to create "industrial energy boutiques." We employ a rigorous traceability system, ensuring every component's journey—from raw materials to the final inspection—is documented for absolute reliability.

Adapting GNM1EL technology to the world's most demanding sectors
Our GNM1EL breakers solve frequent tripping issues in water pump units. Combined with smart capacitors, they enhance energy efficiency and ensure continuous operation in moisture-prone environments.
Handling diverse loads and harsh operating environments, our solutions provide the high reliability required to prevent catastrophic failures in refining and oilfield enterprises.
In the global shift toward decarbonization, GNM1EL breakers are critical for protecting photovoltaic microgrids and building-integrated systems, reducing system losses and improving generation efficiency.
Eco-friendly materials (compliant with EU RoHS) ensure that our breakers provide safe, non-toxic protection for hotel guests while integrating seamlessly with smart home panels.
Reducing probability of electrical accidents caused by voltage fluctuations or electrostatic discharge, providing the stability required for sensitive semiconductor and electronic assembly lines.
At Igoye Energy, we are not just manufacturing hardware; we are engineering the future of the Smart Grid. Our current R&D focuses on integrating IoT (Internet of Things) capabilities into the GNM1EL series.
We understand that different regions have unique electrical codes (e.g., BS 7671 in the UK or NEC in the US). Our technical team provides bespoke consultation to ensure that GNM1EL installations meet local safety requirements, including specific trip curves and terminal configurations.
Standard MCCBs protect against overloads and short circuits. The GNM1EL series adds a "Residual Current" module that protects against earth leakage, preventing electric shocks and fire hazards caused by insulation breakdown.
Yes. Igoye Energy products, including the GNM1EL series, are manufactured using non-hazardous materials (no lead, mercury, or cadmium) and comply with major international quality and safety certifications.
While the GNM1EL is primarily an AC breaker, we offer specialized DC-compatible molded case circuit breakers (like the GNM1DC series) specifically designed for the unique quenching requirements of photovoltaic arrays.
