Sealed packet switch GPP2-16 / H2
Packet switches PP (sealed packet switches GPP) & nbsp; are designed to work in electrical circuits up to 380V AC with a frequency of 50, 60Hz and 400Hz and up to 220V DC as:
- input switches in the control circuits of electrical power distribution installations;
- hand-operated switching devices for infrequent switching on and off;
- for manual control of asynchronous motors in AC electrical circuits.
