The SITAS 4AM6142-5AT10-0FA1 is a 1600VA single-phase control transformer converting a 400V line-to-neutral supply to 230V at 6.96A for industrial control circuits. Designed for the most common European industrial distribution voltage, the 5AT10 variant delivers the full 4AM6142 platform performance in the standard 400V-to-control-voltage configuration.

Electrical Performance

Rated at 1,600VA continuous with a short-time power rating of 7,300VA (S6 duty) — over 4.5x headroom for high-inrush loads. The laminated EI core achieves approximately 96 percent efficiency at full load. Primary taps at 380/400/420V (±5 percent) accommodate voltage fluctuations in three-phase distribution networks. Full galvanic isolation via II0 vector group.

Mechanical Design

Substantial 164x176x138mm IP00 open-frame construction for enclosure installation. Screw terminals on a screw-mount chassis. Class B (130 C) insulation system, rated for 40 C ambient. Weighs approximately 28 kg.

Application

The standard choice for European industrial control panels, machine tool automation, and process control systems where 400V three-phase is the building supply and 230V control power is required for contactors, relays, PLCs, and HMIs.
