What this 63 A 4-pole B-curve MCB does in the panel
The 6 kA breaking capacity per EN 60898 covers most distribution board faults; if your panel has a higher prospective fault current, watch the 5 kA rating under UL 1077 and CSA C22.2 No.235. Terminal torque spec is 2.5 to 3.5 N·m — don't overtighten, the screw terminals accept solid or stranded up to 35 mm².
DIN rail footprint and wiring constraints
That's a standard 4-pole MCB footprint — drops into any DIN-rail enclosure with 4 module spaces. Sealable, with touch protection on the terminals. Humidity derating applies above 55 °C per the spec table.
Approvals and compliance signals
Rated per EN 60898 at 6 kA, per UL 1077 and CSA C22.2 No.235 at 5 kA. Overvoltage category III. Energy limiting class 3. Halogen-free and silicon-free construction. Designation per DIN EN 61346-2 and DIN EN 81346-2 is F. The 5SY6CC design variant is the specific internal construction for this order code.
