Hmm, they don't have any relays higher then 30 amps for the NC side?

What the heck do you need more than 30A NC for? I can't even remember ever needing the NC contacts in an automotive application, much less 30A of NC current.

Wouldn't 4-pole work fine for this application?

Isn't NC the part we use? NC is activated by trigger no?

NO is the side we always use, so that the circuit is complete upon energizing. NC side is only used to de-activate a circuit by energizing it (like very basic 2-step systems that de-energize the trailing coils during the 2-step)

NC is only found on 5-post relays. NO is on all (standard) relays.

Guess in electrical NC and NO reference different things. Was thinking NC means "off" when not energized the same way in a boost controller solenoid means no flow. Instead it means circuit is closed so circuit is complete and flowing unlike a broken open circuit. Thanks for clearing that up. All the relays are the same so I haven't looked at the diagram in years.

I've used it for boost controller failsafes to kill the boost upon trigger.
