PRODUCTS DETAILS

Low voltage AC vacuum circuit breaker for mining1. This product has the characteristics of high analysis ability, low temperature, long life, convenient structure adjustment, safety and reliability. This product is mainly used in low-voltage power grids to distribute electric energy, protect power supply equipment and feeder lines, and can also be used as a large-capacity motor for infrequent starting, which is more suitable for use in mine flameproof feeder switches. 2. The circuit breakers of this series are all electromagnetic closing and mechanically maintained 3. The opening types include: separate trip opening, undervoltage trip opening, and manual trip openingThis series of vacuum circuit breakers are mainly suitable for industrial and mining enterprises, power plants, substations and frequent operation with AC 50HZ, voltage 1140V and below. In the power supply network, it forms various power distribution switches with various sub-protection devices, and is especially suitable for composing mine flameproof vacuum feed switches or low-voltage side vacuum feed switches of mobile substations. Mainly used for the protection and control of electrical equipment.This series of vacuum circuit breakers are mainly suitable for industrial and mining enterprises, power plants, substations and frequent operation with AC 50HZ, voltage 1140V and below.
