If you maintain industrial control panels, a relay failure can bring a line to a halt. The challenge is finding a replacement that matches your system's specifications at a price that fits your parts budget. This open-box INDUSTRIAL SSR-40DA relay, listed at $8.00, gives you a specific model and voltage rating to evaluate.
Quick verdict
The INDUSTRIAL SSR-40DA relay is a 24/480V unit in new, open-box condition. At $8.00, it's an $8.00 spare part, so the price is directly stated. If you're after a sealed, factory-fresh relay, this isn't it. But if you're looking for a backup part at a fixed price, this could be practical.
Who it suits
This relay is suited to a technician, engineer, or hobbyist who already knows their system requires an SSR-40DA relay with a 24/480V rating. It's also a reasonable choice for someone building a kit of spare parts without spending much. If you need a brand-new unit in an unopened box, you'll want to look elsewhere, since this one is open-box.
What stands out from the listed details
The listing names the brand as INDUSTRIAL, the model as SSR-40DA, and the voltage as 24/480V. The condition is explicitly "new - open box." The price is $8.00, which is a clear, stated cost for an industrial relay.

This unit's model number and voltage rating are the key facts. If your equipment uses a 24/480V SSR-40DA relay, this spare is designed for that kind of application. The open-box condition is the main limitation-it's not a sealed, pristine package, so the box and maybe the unit itself will show some signs of handling. On the positive side, the $8.00 price is low enough that you can keep it in your parts drawer without tying up a lot of money.
Meaningful trade-offs
The most significant trade-off is the open-box packaging. While the condition reads "new," open-box items have been unpacked before, so you might see minor handling marks. Another consideration is that the listing only confirms the model and the 24/480V rating; other specs like amperage or control voltage aren't provided, so matching by model number is the safe approach. For the price, though, the financial commitment is small.
Bottom line
The open-box INDUSTRIAL SSR-40DA relay at $8.00 is a simple choice: if you need a 24/480V SSR-40DA and can accept open-box condition, this is a sensible spare. Just remember that the model and voltage are your compatibility guide. For the asking price, it's a reasonable part to keep in reserve.
