The operating shafts of switching devices
have bronze bearings so that any rusting-in
will be ruled out |
| • |
Contacts and profile blades are made
of drawn electrolytic copper |
| • |
Conducting paths have 10 µm electro-silverplating |
| • |
Rust-resistant compression springs
adequate contact pressure |
| • |
The striker sides of the 1250 A, 1600
A, and 2500 A disconnectors have contact
inserts with self-lubricating silver-graphite
facings, disconnector mounting frames that
are galvanised and passivated in chromic
acid |
| • |
All disconnectors and earthing switches
are equipped with continuous operating
shafts (ø=30 mm) that allows mounting
