Tips: What are the reasons for choosing ATO vacuum circuit breaker?

• ATO 12kV vacuum circuit creaker has the reliable interlocking function. Designed into fore and rear separate structure, it is used as the unit for fixed installation, in addition, it can be assembled with the chassis, as the individual handcart.
• Employing the mature APG technique and advanced epoxy-resin solid encapsulation technology, the vacuum arc-extinguishing chamber, main conductive circuit, insulating support, etc. are combined organically to form a integrated solid-encapsulated pole, the surface of vacuum arc-extinguishing chamber is not affected with the environment, so as to really realize the maintenance free.
