Electrical Data

690 V AC / 630 A
rated insulation voltage 800 V
rated surge withstand capacity 6 kV

conditional rated short circuit current 50 kA (with fuse links gL/gG)
switching capacity / application categories AC23 B (400 V),
AC22 B (690 V), AC21 B (690 V), DC22 B (440V), DC21 B (440 V),

for fuse links to IEC 60269-2-1 (I) / DIN VDE 0636-201 size 1 up to 48 W

AC20B (1000 V), DC20B (1000 V) pollution degree 2
visible instruction necessary; if application more than DC 440V /AC 690V:
do not operate under load

DC specifications: 2 current paths (L1, L3) in series.



According to the AC and DC switching characteristics and in consideration of the overload conditions, the following distances to earth metal parts have to be provided.
- top 300mm, side 130mm
By using as a disconnector (switching not under load) the mentioned distances are not applicable.

Power dissipation:
The power dissipation of the device results in 38,4 W at a typical
load with 80 % of the nominal current.
(The power dissipation is 60 W for application at nominal current.)
