Isolate the switch
in GN
- 1.5 / S200-1.6 family |
| 1.The use of the products
and scope of application:
GN -
1.5 / S200-1.6 family isolate switch (hereafter
referred to as switch) suitable for and exchange
50/60 Hz mainly, specified voltage 1140 Vs,
the supreme voltage is 1500V, the specified
electric current is a device in one of 200
As. Except that the ones that make and isolate
power are used, also can used in frequent
putting through and assign to and break the
circuit.
2.Technological characteristic of
the switch:
2.1 switch for person who
open, main circuit it counts to be three very
much, operation mode as manual very much,
the switch attaches three fuse box seat and
enclosure as the switch of a small-scale relay
connected with the body very much. The design
of this switch has fully absorbed domestic
and international advanced technology, and
actual conditions and technological level
of combining our country have made very good
result, have the characteristics that the
project organization rational, aesthetic in
appearance, works is reliable .
