magrini galileo circuit breakers

[jwparker]

Im attempting to obtain information regarding setting the LSI settings on magrini galileo circuit breakers. Has anyone ever used/heard of these before? Specially type MG. I know this is a shot in the dark.

Square D should have all the info for those. But figuring out settings should be easy if you want to post your specific question.

Thanks, I know what the settings should be, its physically adjusting them is what im questioning.

Square D has Merlin Gerin breakers, not sure of Magrini Galileo.

A google search says Maglini Galileo is (or was) an Italian company. (No prizes for guessing). Its HV breaker business was taken over by Siemens. Not sure of its LV breaker business.

I was not thinking of Merlin Gerin, but you are correct Maglini Galileo made breakers for Siemens, not SQ-D. My bad.

Yes, its a 15kV oil circuit breaker, meaning I maybe should be looking for the trip unit for adjusting settings, not this unit.

15 kV breakers do not have built in trip units. They use separate relays with CTs and those could be any one's. You need to get the mfr., model and rating of those.
