Siemens · 2010
General data
Footnotes for page 14:
1) For 3RV16 voltage transformer circuit breakers see more
"Technical specifications".
2) Above +60 °C current reduction.
3) 500 V with molded-plastic enclosure.
4) Terminal compartment IP00 (exception: 3RV10 11-..2. motor starter
protectors with Cage Clamp terminals degree of protection IP20).
5) With appropriate accessories.
Footnotes for page 15:
1) Cable lug and busbar connection possible after removing the box
terminals.
2) If bars larger than 12 mm x 10 mm are connected, a 3RT19 46-4EA1
terminal cover is needed to comply with the phase clearance.
3) If conductors larger than 25 mm
2
are connected, a 3RT19 46-4EA1
terminal cover is needed to comply with the phase clearance.
4) If two different conductor cross-sections are connected to one clamping
point, both cross-sections must lie in the range specified. If identical
cross-sections are used, this restriction does not apply.
5) For corresponding 8WA2 803 or 8WA2 880 opening tools
see Catalog LV 1, Chapter 5 "Protection Equipment" -->
"3RV Motor Starter Protectors up to 100 A" --> "Accessories".
6) With conductor cross-sections of ≤ 1mm
2
an "insulation stop" must be
used (see Catalog LV 1, Chapter 3, "Accessories and Spare Parts".
