Description cont..
Padlocking in the “tripped” position is possible using the padlocking device (not
supplied)
n
Protected against nuisance tripping due to transient overvoltages (lightning,
switchgear operation on the network, etc.)
n
Impulse withstand level 8/20 µs:
AC and A classes:
- 250 A for instantaneous
