When you're choosing among relays, contactors, and industrial switches, the real question is how much relay you need. One of these is a low-cost spare for a basic AC circuit, and the other is a more capable industrial control relay. The right choice depends on the size of your contact bank and the scale of your switching duties.
Quick Verdict
The INDUSTRIAL SPARE AC250V6A is the pick when you want a straightforward relay and you don't need a large contact bank. The SQUARE D 8501 X080 is the pick when your panel needs more contact capacity.

Product Notes
INDUSTRIAL SPARE Relay
This relay is the only one of the two listed as new open-box, and that makes it the better fit if you want a unit that hasn't been installed before. The AC250V6A rating identifies it as a simple AC relay for 250V/6A circuits. Since the relay is defined by that rating, it works well when you already know your wiring plan and need an uncomplicated spare. The new open-box condition also means the packaging may not be factory-sealed, so shoppers who insist on a sealed retail box will need to weigh that. If your application is a basic AC switching job, this relay keeps the decision simple.
SQUARE D 8501 X080 Relay
The Square D 8501 X080 is a heavy-duty NEMA industrial control relay with eight normally closed contacts on an eight-pole base that can be expanded up to 12 poles. It also has a 10A thermal current rating and a 600V AC maximum, giving it a larger operating envelope for control panels. The trade-off is the used condition: this is a pre-owned unit that may show minor cosmetic wear from handling or installation. It remains functional and reliable for panel installation, but if you specifically want unused parts, the used condition is the detail to consider. For panels that need more contact capacity, this relay provides it.
Final Choice by Use Case
Choose the INDUSTRIAL SPARE relay for a basic AC relay application where a simple unit is all you need. Choose the SQUARE D 8501 X080 when your control panel needs the extra capability of a heavy-duty relay.
