IntermaticFF5MH Timer Brushed Metal Finish

Can this work for turning off for five minutes instead of turning on?

Once the timer is set for say 5 minutes can it be manually overridden to turn it off before the set time?

I have one of these on my travel trailer fuel pump but it no longer counts down. Would this be okay to replace the existing one installed under coach?

This item intermatic ff5m 5-minute timer. can anyone advise the ampere rating? i have taken one. need to know rating to decide for next.
