Product Description

The Siemens 4AM3242-4TN00-0ED0 is a 50 VA SITAS safety isolating transformer housed in an IP54-rated enclosure, delivering 24 V AC at 2.09 A from a 230 V AC supply. Unlike the open-frame IP00 variants, this model provides built-in protection against dust and water splashes, making it suitable for installation outside of control cabinets or in harsh industrial environments.

What the IP54 Enclosure Means in Practice

Dust-protected and splash-proof — can be mounted directly on machinery without an additional cabinet
50 VA continuous rating with 190 VA S6 short-time capability for contactor and solenoid loads
230 V primary with ±5% voltage taps (218/230/242 V) for adapting to site supply conditions
Safety isolating design per EN 61558-2-6 and control transformer standard EN 61558-2-2

Installation and Series Options

Mounts via screws or DIN rail. The IP54 enclosure eliminates the need for a separate protective cabinet, saving panel space and installation time. For installations where the transformer will be placed inside an existing IP-rated cabinet, the open-frame 4AM3242-4TN00-0EA0 (63 VA, IP00, 1.62 kg) offers a more compact and cost-effective alternative within the same SITAS series.
