The CFB3 series miniature circuit breaker is suitable for overload and short circuit protection in AC 50/60Hz, rated voltage up to 230V/400V, and rated current up to 125A lines. It can also be used for infrequent on/off operations of the line under normal conditions. The CFB3-63 series circuit breaker is equipped with accessories such as CFB3-F auxiliary contacts, CFB3-FB auxiliary alarm contacts, CFB3-FL shunt release, CFB3-QY undervoltage release, CFB3-GY overvoltage release, CFB3-GQY overvoltage release, etc., providing convenience for the intelligent control of smart buildings. Overvoltage, undervoltage, and overvoltage/undervoltage are electronic release devices that are assembled and combined with circuit breakers or residual current circuit breakers. They are suitable for AC 50Hz/60Hz circuits with a rated voltage of 230V, and are used to protect against overvoltage, undervoltage, and overvoltage caused by line faults, avoiding damage to electrical equipment or inability to function properly due to fluctuations in grid voltage. The circuit breaker has an isolation function. Compliant with standards: GB/T10963.1, IEC60898-1, GB/T20645.

The ZW7-36 series 36KV 1600A Outdoor HV Vacuum Circuit Breaker is designed for outdoor use in high-voltage power systems operating at 36 KV. It can be used to connect or disconnect the load current, handle overloads, short circuits, and other related functions.

126KV Outdoor high-voltage SF6 circuit breaker is a high-voltage, three-phase AC 50Hz switchgear designed for outdoor use, ideal for controlling and protecting 126kV transmission and transformation systems. Additionally, it can function as a contact breaker and opener group. This circuit breaker utilizes an intelligent arc extinguishing principle that combines thermal expansion with auxiliary blowing, and features a CTB-1 operating mechanism. It meets the standards outlined in GB1984-2003 for AC high-voltage circuit breakers and is compliant with the International Electrotechnical Commission's IEC62271-100:2001 standard for high-voltage AC circuit breakers and control equipment.

The 72.5KV Outdoor high-voltage SF6 ceramic column circuit breaker is designed for controlling and protecting 72.5KV transmission and transformation systems. It operates on a three-phase AC 50HZ outdoor high-voltage switchgear and can function and opener group. By utilizing the intelligent arc extinguishing principle of "thermal expansion+auxiliary blowing" and equipped with a CTB-1 operating mechanism, this circuit breaker meets the standards of GB1984-2003 and International Electrotechnical Commission standard IEC62271-100:2001 for High Voltage AC Circuit Breakers.

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.
