3RV Motor Starter Protectors/Circuit Breakers up to 100 A General data Footnotes for page 5/16: 1) For 3RV16 voltage transformer circuit breakers see more "Technical specifications" . Footnotes for page 5/17 : 1) Cable lug and busbar connection possible after removing the box terminals. 2) Above +60 °C current reduction. 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) 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).
3) If conductors larger than 25 mm 2 are connected, a 3RT19 46-4EA1 terminal cover is needed to comply with the phase clearance. 5) With appropriate accessories. 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 1 mm 2 an "insulation stop" must be used (see Chapter 3 "Contactors and Contactor Assemblies" --> "Accessories").
