3RV Motor Starter Protectors/Circuit Breakers up to 100 A Accessories Mountable accessories 1) Prospective short-circuit current 1) 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. 2) With conductor cross-sections of 1 mm 2 an "insulation stop" must be used; see "Accessories", "Contactors and Contactor Assemblies". 3) For corresponding 8WA2 803 or 8WA2 880 opening tools see "Accessories".
