transformer SITAS; phases: 3; Pn/Pn(S6)(kVA): 1.6 /6.9; Upri(V): Y500-400/D289-230; Usec(V): Y 400 / D 230; Isec(A): 2.3-4.0; F(Hz): 50...60; vector group/shielding winding: IIIIII0 /0; temperature rise/insulation class: 40 /B; IP00; connection: screw/flat-type connection; mounting: screws; EN 61558-2-1, -2-2, -2-4 UL/CSA-recognized control transformer isolation transformer The 4AP 3-phase transformers are implemented as isolating, safety or matching transformers with different primary and secondary voltages and vector groups. They are suitable for a "fuseless design" due to their low inrush current and this is achieved with SIRIUS 3RV motor starter protectors/circuit breakers.
