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 KYN28-12(Z) AC metal-clad switchgear 3.6KV 1250A Medium Voltage Power Distribution Cabinet is designed for use in three-phase AC power systems operating at a rated voltage of 12kV and frequency of 50Hz. This equipment is utilized for the reception and distribution of electric power, as well as for the control, protection, and monitoring of circuits.

Outdoor transformer oil immersed transformer 10kv 20kv 35kv are a newer type of transformer that boasts a better-designed structure and improved performance. Its three core columns, arranged in an equilateral triangle shape, eliminate any air gaps in the magnetic circuit, resulting in tighter windings. The length of the three magnetic circuits is consistent and shorter, and the cross-sectional area of the core columns is closer to a circle. These design improvements lead to enhanced performance, reduced loss, decreased noise, and a better balance of the three components. Additionally, the third harmonic component is reduced. This transformer is well-suited for use in urban and rural areas, industrial and mining enterprise power grids, and is ideal for combination transformers and pre-installed substations.
