The components of the DNH19 series DC1000V 1500V Switch Disconnectors
> GRL DNH19 series DC1000V 1500V Switch Disconnectors ,The DNH19 range of switch-disconnectors from 100A to 1250A is specially designed for DC applications.
The DNH19 switch-disconnectors are designed to offer efficient and reliable performance even in high ambient temperatures and harsh environmental conditions. They are virtually maintenance-free. The unique contact design results in a lower temperature rise.
The HD13 Knife changeover switch is suitable for distribution panels at AC 50HZ ,rated voltage up to AC690V and rated ampere t to 3150A. Used for infrequently manually closing and breaking current circuits, or disconnector switches.With a middle operate handle, the switch is mainly applied in power system, be worked as a load break switch ,don’t cut off the circuit with current.
