The DC Isolating switch is mainly suitable for indoor devices with AC 50/60Hz, rated voltage of 1500V, maximum voltage of 1000V, and rated current of 200A and 400A. In addition to being used as a switching power supply, the DC Isolating switch can also be used to make and break circuits infrequently. It is mainly used in the photovoltaic field.

GRL offers a variety of DC switching solutions :

GRL DNH19 series DC1000V 1500V Isolating switch ,The DNH19 range of Isolating switch from 100A to 1250A is specially designed for DC applications.

The DNH19 Isolating switch 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.
