The KYN28-12(Z) 3.6KV 630A Medium Voltage Electrical Switchgear is designed for 12kV rated voltage and 50Hz rated frequency in three-phase AC power systems. It functions to handle electric energy reception and distribution, as well as to control, protect, and monitor circuits.

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 ZW43-12 series 12kv 630A Outdoor Automatical Vacuum Circuit Breaker are designed for outdoor use, with a rated voltage of 12kV and a frequency of 50Hz. These breakers are highly efficient, handling load currents, overload currents, and short circuit currents in power systems with ease. They are particularly suited for substations, industrial and mining establishments, and urban and rural distribution networks, where they provide protection and control, especially in applications that require frequent operation and automation. These breakers comply with several standards, including GB/T1984 for high-voltage AC circuit breakers, GB/T11022 for high-voltage switchgear and control equipment, and D1402 for AC high-voltage circuit breaker ordering technical conditions. Additionally, the circuit breaker can be paired with a controller to form a coordinated device, enabling remote control, monitoring, communication, and adjustment capabilities.

The KYN28-12(Z) AC metal-clad switchgear 7.2KV 3150A High Current Medium Voltage Electrical Switchgear is designed for use in three-phase AC power systems operating at a rated voltage of 12kV and a frequency of 50Hz. This equipment is utilized to both receive and distribute electric power while also managing, safeguarding, and overseeing electrical circuits.

The ZW7-36 series 40.5KV 1250A Outdoor high-voltage vacuum circuit breaker is a three-phase, 50Hz AC outdoor switchgear designed for 36 KV power distribution and transmission systems, capable of controlling load currents, overloads, short circuits, and other electrical currents by safely switching them on or off.

The DZ20 series plastic shell circuit breaker (hereinafter referred to as the circuit breaker) is suitable for distribution lines with AC 50Hz, rated current up to 1250A, rated insulation voltage of 660V, rated working voltage of 380V (400V) and below, as overload, short circuit and undervoltage protection for distributed electrical energy, lines and power equipment. Among them, the Y, J, and G type circuit breakers with rated currents of 225A and Y type 400A can also be used to protect motors. Under normal circumstances, the circuit breaker can be used for infrequent switching of lines and infrequent starting of motors. The product meets the standards of JB8589, GB14048.2, and IEC947-2.
