I am new to playing with relays...
I have a current which will range from 36v to 54v at 1-3a
I would like to use a relay to switch off the current to a sub circuit once the main circuit voltage crosses 50v.
When I look-up 48v relays I see MUCH higher switching voltage. The one below shows 300V DC @ 16A and sounds like massive overkill to me.

It sounds to me like I should use relays with much lower switching voltage limits (~60v@~3a) and use resistors to make sure that when the circuit voltage crosses the 50v it hits the pickup voltage level of the relay (I'm seeing numbers as low as 3-12v).
Unfortunately we don't know what we don't know. From what I'm expressing does it sound like I have a reasonable idea of how relays work and how to apply them into real world applications? If so, does this plan in particular sound reasonable or is there something else you would advise I look into?
Thank You,
Scott
