Explore our primary line of high-performance fuses, universal circuit breakers, and automatic transfer switches built to international industrial standards.
Analyzing industry adoption cycles, total cost of ownership (TCO) optimization, and supply-chain resilience for commercial power grids.
For remote telecommunications, industrial pump stations, and utility substations, dispatching technicians to manually reset tripped breakers accounts for millions of dollars in annual operating expenditures. Automatic reset circuit breakers (ARCB) eliminate "truck rolls" by automatically testing and recovering from transient faults.
The global push for smart grids demands endpoints that can handle momentary fluctuations. Automatic reset breakers coordinate seamlessly with automated control loops, utilizing microcomputer protection protocols to maintain continuous service under variable harmonic and reactive conditions.
Enterprise procurement specialists require clear evidence of strict validation protocols: mechanical endurance parameters, dielectric breakdown limits, and environmental thermal cycles. Partnering with a comprehensive ODM ensures products conform to domestic national codes before entering local networks.

How our intelligent power distribution systems and automatic reset mechanisms serve global industrial applications.
Igoye provides a comprehensive and reliable solution: intelligent plastic shell motor protection function, effectively solving the problem of frequent tripping during motor start-up and ensuring the normal operation of the pump unit. After a power line failure interruption, the dual power supply will promptly and quickly switch to the backup power supply to restore power supply. Intelligent capacitors automatically compensate for capacity, improve power factor, and reduce losses.
The petrochemical industry has high reliability requirements, large loads, diverse types, and harsh operating environments. Based on years of industry experience, we provide customers with comprehensive distribution solutions, providing reliable guarantees for the transition from speed and scale growth to efficiency and quality, achieving safe, reliable, and economical operation of the distribution system.
We provide intelligent products such as universal circuit breakers and electronic plastic shells to ensure power supply continuity, realizing interconnection, real-time monitoring, and intelligence of underlying components. Customers can access electrical data in real time through PC and mobile terminals, making it convenient to monitor the power situation and energy management.
We upgrade and optimize low-voltage distribution solutions for hotel systems. The new series of distribution products provided do not contain harmful substances such as benzene, cadmium, lead, mercury, etc., and comply with the EU ROHS environmental certification, making them safer and more environmentally friendly. The main products include a full range of ACB, MCCB, ATS dual power switches, and MCBs.
Chemical enterprises require large scale, strong continuity, and high demands for distribution automation. Therefore, higher requirements are put forward for power supply continuity, safety, and reliability. By calculating various parameters of the system, selecting distribution protection devices, and using microcomputer protection, production safety is assured.
Low voltage switchgear, as an important component of the distribution network, is difficult to expand due to the wide variety of cabinet types on the market. State Grid Corporation of China has begun to promote the standardization of low-voltage switchgear. Through standardized design, not only can the overall quality of low-voltage distribution cabinets be improved, but user satisfaction can also be enhanced.
Whether it is large-scale photovoltaic power plants, building-integrated photovoltaics, or intelligent microgrids, our custom circuit breakers and high-voltage fuses reduce system losses, reduce installation costs, and improve system power generation efficiency under high-voltage DC environments.
Providing reliable guarantees for the stable and reliable operation of power supply and distribution systems. Focus on preventing power quality accidents, electrical equipment accidents, and operational faults. Establishing a comprehensive monitoring system greatly reduces the probability of electrical accidents.
Industrial automatic reset circuit breakers operate on two distinct topological frameworks to detect and interrupt overload conditions: bimetallic thermal-magnetic mechanisms and microprocessor-controlled electronic sensing relays.
In standard thermal-magnetic breakers, overcurrent conditions generate heat, inducing mechanical deflection in a calibrated bimetallic strip. Once the deflection threshold is exceeded, the mechanical latch releases. The automatic reset mechanism utilizes a dedicated return coil or motor-driven actuator that forces the contacts to re-engage after a predetermined cooling cycle. However, this method is sensitive to ambient temperature fluctuations and requires derating curves.
Conversely, our electronic auto-reset breakers process current waves in real-time through an integrated Current Transformer (CT). When microcontrollers detect current surges, they isolate the circuit using high-speed solenoid actuators. The subsequent reset sequence is dynamically governed by a firmware algorithm that measures residual impedance, ensuring the breaker does not attempt to close into a permanent hard short circuit, which could compromise system components.
For custom ODM projects, matching the trip curve to the load profile is essential to prevent nuisance tripping while ensuring protection. We customize units based on internationally recognized IEC standards:
Furthermore, our engineering teams balance Ultimate Short-Circuit Breaking Capacity (Icu) and Service Short-Circuit Breaking Capacity (Ics). Our premier industrial breakers maintain an Ics of 100% Icu, meaning the breaker can withstand multiple fault currents without degrading critical contact assemblies.
To endure the harsh environments of chemical processing plants and outdoor solar farms, our enclosure systems utilize premium thermoplastics engineered for high dielectric strength and structural integrity. All molded cases conform to the UL94-V0 flammability class, ensuring self-extinguishing capabilities under extreme thermal stress.
We supply terminal enclosures ranging from IP20 for standardized control cabinets up to hermetically sealed IP66 assemblies designed to resist heavy salt-spray, moisture, and corrosive chemical gases. Internal electrical contacts are finished with silver alloy compounds (AgNi or AgSnO2), providing minimal contact resistance and outstanding arc erosion resistance over more than 20,000 mechanical operation cycles.
Building a resilient supply chain requires strong quality control measures at every step of production. Our facility uses automated optical inspection (AOI) systems alongside real-time coordinate measuring machines to verify tolerances down to the micron. With complete digital mapping of every component batch, we provide our OEM clients with trace data that meets modern aerospace and medical power requirements.
