Panel Fit & Coordination
The DS201MC20A30: Mounts on standard 35 mm DIN rail per EN 60715. The 20 A C-curve coordinates downstream of a higher-rated upstream device (typically a 40–63 A S-curve or a 25 A gG fuse) for selective coordination in a final-subcircuit position. The DS201 M series shares the same physical footprint as the SH200 series, so a panel laid out for SH202T-C20 accepts this unit without re-drilling or busbar rework — verify terminal pitch matches the existing busbar comb if retrofitting.
