Folks,
I'm adding anABB SACE S5 400a shunt-trip - for eventual hookup to Batrium. I want to make sure I set it to the 'max'. You'll notice at the bottom there is lm MIN - MAX and lth MIN-MAX....
Note: This is a 300a picture but I bought a 400a 2 pole replacement as 300a is not enough. But the 400a looks the same - e.g. S5.
If I understand it correctly, the lm is a formula for seconds to trip? and lth looks like max amps. I want 300a + 0.5-1sec'ish delay - so if set both of these to MAX to get 300a with longest time delay I'm guessing I'll be operating at 300a at 1 second or so.
Can someone explain or justconfirm that setting these both to MAX will indeed be in the relm of 300amps @ 1sec 'kind of thing'. I don't care about 0.5secs vs 1sec (i.e. I don't need it to be super sensitive) but I do care about 5+ secs (enough to start a fire)... so I don't want to shoot myself in the foot for basic ignorance on how this works
Thanks in advance
