Transformer, 3-ph. PN/PN(kVA) 1/3.5, Upri(V) Y500-400/D289-230, Usec(V) Y 400/D230

TRANSFORMER SITAS; PHASES:3; PN/PN(S6)(KVA):1 /3,5; UPRI(V):Y500-400/D289-230; USEC(V):Y 400 / D 230; ISEC(A):1,44-2,50; F(HZ):50...60; VECTOR GR./SHIELD WNG.:IIIIII0 /0; TA/ISOKL:40 /B; IP00; TYPE OF TERMINALS:SCREW/TAB CONNECTION; INSTALLATION:SCREW; EN 61558-2-1, -2-2, -2-4 UL/CSA-RECOGNIZED CONTROL CIRCUIT 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.
