I'm having such a hard time finding DPNC 100A contactors that I'm debating which is better: using 2 paralled 50A contacts or using 2 SPNC relays. ======================================== No luck finding anything rated higher than 50A, sorry. Would dropping the DIN rail mount get you anywhere? As far as two 100A relays or parallel 50A relays, my amateur opinion would be to use two 100A relays. With parallel relay contacts you have to worry about getting equal current sharing over the life of the relay in your apparatus, and I think that that is hard to guarantee. -- Regards, Carl Ijames
