Selection Notes

This 20 A C-curve device is sized for the heaviest motor or transformer-type load the DS-ARC1 range covers, tripping magnetically at 5 to 10 times In rather than the tighter 3-to-5 times In band of the B20 A30 version. If the 20 A circuit is purely resistive, the B-curve equivalent gives better short-circuit discrimination. Lower-current circuits with similar inrush characteristics step down to the 16, 13, 10 or 6 A versions in the same C-curve line.
