Schneider Electric 9070TF50D1 Time Delay Relay

Schneider Electric’s Square D 9070TF50D1 is a 50 VA, single‑phase industrial control transformer that provides a 120 VAC control supply from a dual primary input of 240/480 VAC, making it ideal for powering relays, timers, and contactors in motor control panels. Built with copper windings, a 105°C insulation class, and a rated temperature rise of 55°C, this compact transformer measures roughly 3.0 in wide, 3.09 in deep, and 4.0 in tall, and it incorporates a top‑mounted fuse block for convenient protection in a single unit. Operating at 50/60 Hz, the 9070TF50D1 is UL and CSA listed, with secondary voltage commonly specified as 110/115/120 VAC variants to suit different control circuits derived from a 240/480 VAC source. The enclosed form factor and fuse‑block integration simplify panel layouts, reducing the need for separate safety devices in many control installations. Typical applications include machine control panels, conveyors, and automation enclosures where a local, ready‑to‑use 120 VAC control supply is needed from higher‑voltage power sources.
