Square D 9070T50D1 Industrial Transformer: What to Check Before You Commit

This open-box Square D / Schneider Electric control transformer sells for USD 59.99 and includes the original carton and instructions, but it ships without voltage selection jumper clips. Here's what to weigh before buying.

Last updated Aug 17, 2026

Choosing an industrial control transformer usually starts with two questions: how much load will it carry, and how will you configure the voltage taps? The Square D 9070T50D1 Industrial Transformer - No Jumper Clips - Transformer Only forces you to answer both yourself, because it arrives without the clips that select the primary voltage. That makes this listing different from a typical packaged transformer, and it changes how you plan the installation.

Quick verdict

If you need a Square D / Schneider Electric control transformer, the 9070T50D1 at USD 59.99 is a concrete option. The listed price is straightforward, and the brand is Square D / Schneider Electric. For a transformer you will wire into an existing control panel, this price point is worth a close look.

Who it suits

This unit suits a buyer who wants a Square D / Schneider Electric control transformer for a project where terminal wiring is already part of the plan. If you prefer a complete drop-in kit, this may not be the right fit. It also works well if you are replacing a failed control transformer in an existing panel and already have the mounting and wiring hardware in place. Buyers who are new to control wiring should be prepared for a learning curve.

What stands out from the listed details

The description lists multiple primary and secondary voltage options: 220/440, 230/460, 240/480 VAC primary and 110/115/120 VAC secondary at 50/60 Hz. That flexibility is useful in multi-voltage setups. The package includes the original carton and installation instructions, which helps you get started. However, the description says 100 VA (0.1 kVA) while a separate product detail says 1 kVA, so the power rating is not clearly defined. Confirm the actual rating before relying on it for your load.

Meaningful trade-offs

Because this is an open-box unit, the packaging may show wear even if the transformer itself is new. The description asks you to review all photos carefully, which is a sign that the visual condition matters. Also, since this is an open-box item, the included items are exactly what the description lists, so it's wise to check that you have everything you need before starting the wiring.

Bottom line

If you already understand what this transformer can do, it's a workable buy. Review the photos and the full description before deciding.
