It sits in the S200 series, a standard DIN-rail mount platform for branch-circuit protection in distribution panels and load centers. The K-curve is designed for inductive and motor loads, tripping between 10 and 14 times rated current on short circuits — a tighter band than the Z-curve but wider than the B-curve, giving it selectivity with downstream motor starters while still protecting the cable.
