4AU3032-8BC40-0HC0 3-PH. SITAS-TRANSFORMER

TRANSFORMER SITAS; PHASES:3; PN/PN(S6)(KVA):5 /28; UPRI(V):Y500-400/D289-230; USEC(V):Y 400 / D 230; ISEC(A):7,22-12,5; F(HZ):50…60; VECTOR GR./SHIELD WNG.:IIIIII0 /0; TA/ISOKL:55 /H; IP23; TYPE OF TERMINALS:SCREW CONNECTION; INSTALLATION:SCREW; EN 61558-2-1, -2-2, -2-4 >UL/CSA-RECOGNIZED< >CONTROL CIRCUIT TRANSFORMER< >ISOLATION TRANSFORMER< The 4AU 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.
