When shopping for relays, contactors, and industrial switches, the part number usually narrows down the function, but the buying decision often comes down to condition and fit for the panel at hand. The Dayton Transformer Relay 2E555 is a good example: it is a single-pole power relay listed at USD 49.99, described as New Old Stock and presented as 'Listed as New opened box.' In other words, you are getting a new-old-stock relay with an opened carton, so the visual condition in the listing photos matters.
Dayton Transformer Relay 2E555

This one-pole power relay is offered at USD 49.99 and is described as New Old Stock in an opened box. The heavy-duty designation and the commercial/industrial application scope make this a suitable choice when you need a single-pole power relay for control equipment. The trade-off: the opened-box status means this is not a sealed, untouched purchase, and the listing photos are the reference for condition.
Quick verdict
If your control panel needs a one-pole power relay and you are comfortable with an open-box New Old Stock item, the Dayton Transformer Relay 2E555 is a reasonable pick at USD 49.99. Its listed attributes point to a heavy-duty relay intended for commercial, control equipment panels, and industrial use, which matches a straightforward single-pole relay application.
Who it suits
This relay suits someone who already knows the circuit calls for a single-pole power relay and who wants a named part with a heavy-duty profile. Because the listed attributes emphasize the relay type, buyers should match it against their known circuit requirements before purchase.
What stands out from the listed details
The confirmed details center on a heavy-duty single-pole power relay for commercial, control equipment panels, and industrial settings. The price is listed at USD 49.99. The New Old Stock label explains how the unit is being offered, while the 'opened box' note is the honest caveat that shapes the buying decision.
Meaningful trade-offs
The main trade-off is condition. The listing presents the relay as new old stock and notes that the box has been opened; the description also points to the pictures for condition and invites questions. That means the relay may show handling marks, but the photo set is the visual evidence available. For a buyer who wants a sealed, untouched part, the open-box status is the point to weigh carefully.
Bottom line
The Dayton Transformer Relay 2E555 is worth considering when your application calls for a single-pole power relay and the open-box New Old Stock condition is acceptable to you. At USD 49.99, its heavy-duty orientation and intended commercial/industrial use make it a straightforward candidate in the relay, contactor, and industrial switch space.
