Interrupting rating is 6 kA at 277 VAC and 10 kA at 60 VDC. The 6 kA AC figure is the standard for residential and light commercial panelboards in most IEC markets; the 10 kA DC rating covers battery-backed control circuits and DC bus distribution in the same panel. ## How it compares to the 40 A sibling The S201M-C40 shares the same 1-pole DIN-rail footprint, same 277 VAC / 60 VDC voltage ceiling, and same 6 kA interrupting rating. The only difference is the current rating — 40 A instead of 20 A. ## Panel integration note The 1-pole width (roughly 17.5 mm) means it occupies one module position in a standard distribution board. Busbar comb can be fed through the top or bottom terminals; the S200M series accepts pin or fork busbar lugs without adapters.","metaTitle":"S201M-C20 1-Pole C-Curve MCB, 20 A, 6 kA, DIN Rail","metaDescription":"S201M-C20 miniature circuit breaker, 1-pole, Trip Curve C, 20 A, 277 VAC / 60 VDC, 6 kA interrupting rating.
