Allen-Bradley 1497-E-M4-3-N Control Circuit Transformer

Allen-Bradley 1497-E-M4-3-N is a 250 VA control circuit transformer that derives low‑voltage control power from a 380/400/415 VAC supply. It features a multi‑tap primary (380/400/415 V) and a dual-secondary output selectable as 115 V or 230 V at 50 Hz, enabling flexible integration in industrial control panels. The unit provides two primary fuse blocks and one secondary fuse block to protect the circuits, and its service is rated for 50 Hz operation with a continuous 250 VA rating. As a member of the 1497 family, the transformer is intended for machine control and automation applications where isolated control power is required from higher‑voltage mains; its 115/230 V secondary supports common control loads, while the 380–415 V primary is compatible with many regional electrical standards. Listings frequently reference UL, CE, CUL, and KC marks, reflecting broad compliance.
