1)
"Technical Specifications" for 3RV16 voltage transformer circuit breakers,
see page 7/23
.
2)
If two different conductor cross-sections are connected to one clamping
point, both cross-sections must be in the range specified.
3)
Cable lug and busbar connection possible after removing the box
terminals.
4)
If bars larger than 12 mm x 10 mm are connected, a 3RT2946-4EA2 cover
is needed to maintain the required phase clearance,
see page 7/47
.
5)
When conductors larger than 25 mm
2
are connected, the 3RT2946-4EA2
cover is needed to maintain the required phase clearance,
