690 V AC / 630 A
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 (440 V), DC21 B (440 V),
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, L2) in series
for fuse links to IEC 60269-2-1 (I) / DIN VDE 0636-201 size 3 up to 48 W
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 23 W at a typical
load with 80 % of the nominal current.
(The power dissipation is 36 W for application at nominal current.)
Degree of protection IP30 (front side); degree of protection near terminal depends on installation
