China Medium Voltage Circuit Breaker Manufacturer, Supplier, Factory

Product Overview This circuit breaker is a low-voltage protection device designed for AC 50/60Hz power distribution networks with rated voltages up to 400V and currents up to 63A, suitable for industrial, commercial, and residential electrical systems. It integrates comprehensive safety and operational safeguards: High-sensitivity Residual Current Detection (RCD) technology provides indirect contact protection to mitigate electric shock risks, while overload long-time delay protection and short-circuit instantaneous tripping ensure precise fault current interruption, preventing equipment damage and fire hazards. The device also supports infrequent circuit switching and intermittent motor start-stop operations, meeting flexible control demands in standard power distribution scenarios. Key Features & Applications Featuring a modular compact design compatible with global power standards, it is ideal for data centers, manufacturing facilities, and building distribution panels, particularly in environments requiring high power continuity and safety. The thermomagnetic dual-protection mechanism guarantees stable overload response and rapid short-circuit breaking, enhanced by 50/60Hz frequency compatibility for robust system reliability. With a durable construction and rail-mounted quick installation, it serves as a reliable solution for modern smart grids, balancing safety, efficiency, and ease of maintenance.

The GW5 outdoor isolation switch is a high-voltage electrical device designed to meet specific structural requirements. It consists of three independent single-phase isolation switches, making it a versatile and reliable option for various applications. The device complies with the standards outlined in the JB520-64 "AC High Voltage Isolation Switch" and features an additional grounding knife device for added safety. The CS-G manual operating mechanism is available in three variations: ungrounded, single-grounded, and double-grounded, providing users with options to suit their needs.

The 35kv European type Outdoor prefabricated Substation is widely used in urban power grid renovation, residential communities, high-rise buildings, industrial and mining, hotels, shopping malls, airports, railways, oil fields, docks, highways, and temporary electrical facilities, both indoors and outdoors.

The advancement of society, economy, and technology has led to increased complexity in engineering construction. There is a growing demand for compact, low-maintenance, and intelligent switch products. Both domestic and foreign switch manufacturers are actively developing 12KV 1600A Medium Voltage Gas Insulated Electrical Switchgear (C-GIS), also known as gas-insulated switchgear. Gas-insulated switchgear refers to the encapsulation of high-voltage components, such as busbars, circuit breakers, isolating switches, and power cables, within a shell that maintains a lower gas pressure.

126KV 1250A Neutral point disconneetor is specifically engineered for application in high-voltage transmission lines operating under no-load conditions. Its primary function is to provide electrical isolation during the maintenance of circuit breakers and other associated equipment, thereby ensuring compliance with insulation distance requirements and enhancing overall operational safety.
