Siemens · 10/2015 3 3WL1 Air Circuit Breakers Introduction Breaking capacity * Designations according to IEC 60947-2, Appendix K. 1) Size II with I n max ≤ 2500 A. 2) Size II with I n max = 3200 A and In max = 4000 A. 3) At a rated voltage of ≥ 690 V, the I cw value of the circuit breaker cannot be greater than the Icu or Ics value at 690 V. 4) Rated operational voltage U drawout breakers) permits stacking of six SOOA or 1200A breakers or four 2000A breakers in a standard switchboard. Th1s packaging is made possible by the insulated-encased construction and thermal performance of the SB breaker. Even when operated at 100% of the frame rating, no additional ventilation is required for the 1200A and 2000A frames. Siemens - podręczniki, broszury, katalogi dla klientów przemysłowych breakers are environmental-friendly: As far as material selec-tion and manufacturing methods are concerned • Environmentally neutral in operation and during switching operations • Easy to dispose of at the end of their service life 3AH Vacuum Circuit-Breakers Description 3AH Vacuum Circuit-Breakers R-HG11-059a eps Siemens 8BJ50 medium-voltage 3AK vacuum circuit-breaker modules are 3-pole interior circuit-breakers for a ratedvoltage range of 7.2 kV - 17.5 kV.Under normal operating conditions, the vacuum circuit-breaker modules are maintenance-free up to 10 000 operating cycles.Intended use 3AK vacuum circuit-breaker modules are suitable for switching any type of alternatingcurrent circuits under normal operating conditions, such as 6 3AH3 Vacuum Circuit-Breakers · Siemens HG 11.03 · 2018 3AH3 vacuum circuit-breaker from 7.2 kV to 36 kV - The Powerful Circuit-breakers must make and break all currents within the scope of their ratings: From small inductive and capa-citive load currents up to high short-circuit currents, R-HG11-204.tif R_HG11_218.tif SGIM-3268E. 0 reviews.
