Description
Transformer SITAS; phases: 3; Pn/Pn(S6)(kVA): 0.63 /1.8; Upri(V): Y500-400/D289-230; Usec(V): Y 400 / D 230; Isec(A): 0.9-1.57; 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.
