Schneider Electric GV2ME05 and 24VDC Power Supply: 7 Answers From an Emergency Parts Specialist

I coordinate rush orders for an industrial distributor. Not the person who answers on the first ring—I'm the one who gets twenty calls on a Friday afternoon when a machine is down. Over the last decade I've processed more than 200 emergency part orders, and a big share of them involved Schneider Electric products. This FAQ is for anyone searching for the Schneider Electric GV2ME05, a Schneider Electric 24VDC power supply, or a box with a code like N93 written on it.

What is the Schneider Electric GV2ME05?

The Schneider Electric GV2ME05 is a manual motor starter from the TeSys GV2 range. It has an adjustable thermal overload setting from around 0.63 A to 1 A, and it provides overload and short-circuit protection for a small motor branch. You set the dial to match the full-load current on the motor nameplate.

One thing I'd flag: if the motor is drawing more than 1 A, a GV2ME05 is too small. The reset might work, but the starter will keep tripping—and that's the starter doing its job. The fix is a larger setting range, not another GV2ME05.

What is a Schneider Electric 24VDC power supply used for?

A Schneider Electric 24VDC power supply feeds control circuits: PLCs, HMIs, sensors, relays, and small contactor coils. It does not run the motor directly. The GV2ME05 protects the motor; the 24VDC power supply powers the part of the panel that decides what the motor should do.

When people search for a Schneider Electric 24VDC power supply because the control panel is dark, I'd usually start at the DC supply too. But don't replace it from memory. Check the output current rating and input voltage, because a supply that is too small can run fine until several outputs pull current at once and the voltage sags.

Can I use a 24VDC power supply to test a GV2ME05?

Not on the main power side. The GV2ME05 is a manually operated motor starter, so it doesn't need a 24VDC coil to reset or trip. The switching mechanism is mechanical. If you connect a 24VDC power supply to the line terminals, you are not testing the motor starter properly, and you can damage it. Low-voltage DC is only appropriate for checking auxiliary contacts within their rated limits.

What does N93 on a box mean?

Most of the time, it's an asset tag, warehouse bin number, or an internal code that made sense to whoever labeled the box. I've seen N93 written on panels, power supply boxes, and even motor starter packages. It's not usually part of the Schneider Electric product reference.

Trust the label on the actual unit. If someone writes N93 on a box, that doesn't tell you which Schneider Electric 24VDC power supply is inside. Look for the manufacturer's rating label. If the label is gone, take a clear photo and ask a distributor to cross-reference it. The frustrating part is when an overnight charge is wasted because the part number came from a sticky note.

It also helps to search by the exact model instead of N93. Searching N93 by itself brings up unrelated consumer electronics, including an older Nokia N93 phone and its 'how to change time on phone' results. That's not the path to a replacement for an industrial control panel.

How fast can I get a GV2ME05 or a Schneider Electric 24VDC power supply?

It depends on stock location. I've shipped a common 24VDC power supply same-day one week, then seen the same reference on an eight-week factory back-order a month later. The GV2ME05 is stocked fairly widely because it's used in a lot of existing machines, but nobody can honestly give you a universal lead time without checking current inventory.

When the deadline matters, ask the distributor two questions: where is the part shipping from, and what is the actual courier delivery commitment? The last pickup time matters more than the label on the shipping method.

Is rush delivery worth paying for?

I lean yes when the date is fixed and the part is verified. In March 2024, I had a customer need one 24VDC power supply for an acceptance test. Standard delivery would have missed the test window. We paid about $210 for a courier run, and the alternative was losing a $14,000 field test slot. That's an easy call.

But the premium does not fix a wrong reference. If you order a GV2ME05 when you need a GV2ME07, next-day air just gets you the wrong part sooner. Confirm the model, voltage, current range, and accessories before paying for speed. This is why I check every incoming order like it's the one I'd eat the cost of.

What do people forget to ask about a Schneider Electric replacement?

The question I'd add is: what killed the original part? A 24VDC power supply can fail because it reached end of life, but it can also fail because of a shorted load, surge, or high ambient temperature. A motor starter that keeps tripping may indicate an overloaded motor or a jammed machine, not a defective starter.

A client once wanted a same-day 24VDC power supply because they had replaced the same reference twice in four months. The cost analysis said ship it. My gut said ask why. It turned out the real issue was a shorted DC coil elsewhere in the panel. The replacement was necessary, but the wiring fault would have killed it again. Find out what happened before you install the new unit, then put the spare in a labeled box with the real part number—not a mystery code.
