Product Overview The HMB1 Series Residual Current Circuit Breaker is a high-sensitivity safety device designed to protect people and electrical installations against earth leakage faults. Operating in AC 50/60Hz networks, the HMB1 monitors the balance of current between the live and neutral conductors. When a leakage current exceeds the rated sensitivity (due to insulation failure or accidental contact with live parts), the HMB1 trips instantly, cutting off the power supply

Product Overview The NH40 Series Automatic Transfer Switch (ATS) is a critical solution for ensuring uninterruptible power supply in industrial, commercial, and residential environments. Specifically designed to automatically switch between a primary power source (Utility) and a backup source (Generator or Secondary Transformer), the NH40 ensures your critical loads remain energized during a grid failure. With a wide current range from 100A to 3150A, the NH40 integrates the

Product Overview The NB1-63DC Pure DC Air Switch is a specialized miniature circuit breaker (MCB) engineered specifically for the demanding environment of Solar Photovoltaic (PV) systems. Standard AC breakers are designed to extinguish arcs at the "zero-crossing" of an AC cycle; however, DC current is continuous, making arcs significantly harder to break. Our NB1-63DC series features a specialized internal magnetic and cooling structure that forces the DC arc into the

Product Overview The Smart WiFi MCB represents the next generation of electrical safety and home automation. Operating on a 2.4GHz WiFi network, this device combines the reliable overcurrent and short-circuit protection of a traditional Miniature Circuit Breaker with the advanced intelligence of IoT technology. Compatible with the Tuya Smart and Smart Life apps, this breaker allows users to monitor real-time power consumption, switch circuits remotely, and set automated

Product OverviewThe Smart WiFi MCB is a revolutionary advancement in residential and industrial circuit protection. It combines the core short-circuit and overload protection of a traditional Miniature Circuit Breaker with the intelligence of modern IoT connectivity.Operating on a standard 2.4GHz WiFi network, this breaker allows users to manage their electrical systems via the Tuya Smart or Smart Life app. Whether you are managing a holiday home, a remote industrial pumping

Product Overview The NB1-63DC Series is a high-performance miniature circuit breaker specifically designed for Solar Photovoltaic (PV) applications. While standard AC breakers fail to extinguish the persistent arcs of direct current, the NB1-63DC features specialized internal magnets and arc-chutes to safely interrupt DC faults. As a critical component in solar combiner boxes and inverter protection circuits, this breaker safeguards your PV modules and wiring against

Product Overview The 100A 3-Phase MCCB is a robust industrial-grade circuit breaker designed to provide comprehensive protection for power distribution systems and motor circuits. Engineered for AC 50/60Hz networks with rated voltages up to 690V, this breaker excels in protecting downstream equipment against overloads, short circuits, and undervoltage conditions. With its compact frame and high-strength thermoset housing, this MCCB is the standard choice for industrial

Product Overview The RW12 Series Outdoor Drop-Out Fuse Cutout is a critical protection device for medium-voltage overhead distribution systems. Engineered to protect distribution transformers and feeder lines from overloads and short-circuit faults, this fuse cutout provides a visible air-gap isolation point, which is essential for line maintenance and safety. When a fault occurs, the fuse link melts and the fuse tube drops down under its own weight, providing an immediate

Product Overview The NM8NDC Series DC MCCB is a specialized circuit breaker engineered specifically for the demands of Direct Current (DC) power systems. Unlike standard AC breakers, the NM8NDC is optimized for the unique arc-quenching requirements of high-voltage solar PV arrays, battery energy storage systems (BESS), and electric vehicle charging infrastructure. Rated for currents from 50A up to 250A, this 2-pole breaker provides essential protection against overloads and
