Many users pick this relay because it carries the Square D brand, a name they have used before.
You will find that the 4 Pack makes it simple to replace relays across several devices.
With the 4 Pack you get enough relays to handle multiple tasks around the workshop.
I appreciate the 4 Pack because it saves time when a relay fails unexpectedly.
