24KV 400A 630A Vacuum Air Load Break Switch

1. FN7 Type Indoor 24KV Vacuum Air Load Break Switch

24kv Three-pole Load Break Switch are designed according to a modular system, parting from a non-load isolator switch (refer to section Non-load isolating switches), whose galvanized steel frame has several drillings that allow the conversion of an isolator switch into a disconnecting switch without any problem, even when

already installed in the field, by simply adding the arcing chambers. This efficient design also allows the easy replace-ability of parts and maintenance.
