This is the sort of breaker you spec into a panel feeding a group of motor contactors or a bank of DC power supplies.
Mounts on standard DIN rail — snaps into the same footprint as any S200 series MCB, so it drops into an existing panel without drilling or adapter plates. The single-pole width keeps fill factor tight; you can pack a 63 A feed alongside lower-amp branches in the same distribution row.

The listed continuous current rating is 63 A. That is the maximum load the breaker is designed to carry without tripping under normal conditions.
Trip Curve K means the magnetic trip threshold is 8 to 12 times the rated current — suited for inductive loads like motors and transformers where inrush current is higher than resistive loads.
Yes — both are 1-pole S200MUC series MCBs on the same DIN-rail footprint with identical voltage ratings (277 VAC / 250 VDC) and interrupting capacities (6 kA AC / 10 kA DC). The only difference is the current rating: 63 A vs 2 A. Physically interchangeable in the same slot, but verify the load side is sized for 63 A before swapping.
