The SITAS 4AM6442-5AT10-0FA0 is the highest continuous power rating in the SITAS control transformer family — 2,000VA — stepping the most common European industrial voltage (400V line-to-neutral) down to 230V at 8.70A. The standard screw-terminal variant for the largest control panels and multi-contactor automation systems.

Electrical Performance

Rated at 2,000VA continuous with a class-leading short-time power rating of 9,700VA (S6 duty) — nearly 5x headroom for the heaviest high-inrush loads. The EI 174/102 laminated core achieves approximately 96 percent efficiency. Primary taps at 380/400/420V (±5 percent). Full galvanic isolation via II0 vector group.

Mechanical Design

Substantial 158x176x164mm 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 25 kg.

Application

The ultimate choice for large European industrial control panels, multi-motor machine tool automation, process control systems, and material handling installations where 400V building supply feeds extensive 230V control circuits at 2000VA.
