Product Description
The SITAS 4AM6142-5AT10-0FA0 is the standard screw-terminal variant of the 400V-to-230V 1600VA control transformer — the most common configuration in European industrial control panels. Sharing the identical electrical performance of the -0FA1 variant, it steps 400V line-to-neutral down to 230V at 6.96A with conventional screw terminals for standard panel wiring practices.
Electrical Performance
Rated at 1,600VA continuous with a short-time power rating of 7,300VA (S6 duty). The laminated EI core achieves approximately 96 percent efficiency. Primary taps at 380/400/420V (±5 percent) handle supply variations. Full galvanic isolation via II0 vector group.
Mechanical Design
Substantial 164x176x138mm IP00 open-frame construction. Screw terminals on a screw-mount chassis — the standard configuration for conventional panel wiring. Class B (130 C) insulation, rated for 40 C ambient. Weighs approximately 28 kg.
Application
The go-to choice for European machine builders, panel shops, and system integrators where 400V three-phase building supply must feed 230V control circuits. Powers contactors, relays, PLCs, and HMIs in standard industrial automation panels.
