The SITAS 4AM4342-8DN00-0EB0 is a 315VA single-phase control transformer designed for industrial control circuits requiring 24V from higher mains voltages. With its 3-tap primary (525/500/480V) and cage-clamp terminals on a DIN rail mount, it suits international machine builders who need fast, tool-free wiring.

Electrical Performance

The EI 105/60 laminated core achieves approximately 90% efficiency at full load with a short-time power rating of 1,120VA (S6 duty) — over 3.5× the continuous rating — for handling high-inrush contactor and relay loads. The II0 vector group provides full galvanic isolation between primary and secondary.

Mechanical Design

Compact 107×111×120mm IP00 open-frame construction for enclosure installation. The 0EB0 variant features cage-clamp spring-loaded terminals for vibration-resistant, maintenance-free connections and DIN rail mounting for quick panel integration. Operating temperature range up to 40°C with Class B (130°C) insulation per IEC 60085.

Application

Typical applications include machine tool control circuits, conveyor system automation, and packaging machinery where 24V control voltage is standard and reliable high-inrush performance is required.
