Siemens 4AP3095-0BJ70-8B Three-Phase Transformer

Siemens 4AP3095-0BJ70-8B is an 8.0 kVA, three‑phase transformer that steps down a high‑voltage three‑phase supply to a 230 V secondary. The primary taps accommodate 500, 480, or 460 VAC, enabling compatibility with a range of regional power systems, while the low‑voltage side delivers 230 VAC at 50/60 Hz. This transformer is suitable for installation in electrical panels, switchgear, and industrial distribution enclosures where reliable isolation and voltage conversion are needed for 230 V loads. The exact part number 4AP3095-0BJ70-8B identifies a Siemens device within the 4AP family, designed for mid‑size distribution tasks in compact cabinet form factors. With its three‑phase design, it helps balance loads and support steady operation of 230 V motors, control circuits, and auxiliary equipment fed from higher‑voltage mains, across global manufacturing environments where 50 Hz or 60 Hz service is encountered.
