It breaks fault currents up to 4.5 kA per EN 60898 and 5 kA per IEC 60947-2, which covers most residential and light commercial panelboard duty.
Occupies 4 modular-width units (72 mm wide) on a DIN rail. Mount in any position. At 40 °C ambient the 63 A rating derates to 59.85 A; at 45 °C it's 57.96 A — factor that into your load schedule if the panel runs warm. IP20 with conductors connected; overvoltage category III, pollution degree 2 — standard for distribution boards.
Rated 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 at 400 V AC. That covers standard residential and light commercial fault levels.
It is a 4-pole C-curve miniature circuit breaker rated 63 A, used for overcurrent and short-circuit protection in residential and infrastructure distribution boards. The C-curve suits mixed loads with moderate inrush — lighting, general-purpose outlets, small motors.
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
Both are 4-pole SENTRON MCBs with the same 4 MW width (72 mm) and DIN-rail mount. The 5SL3463-7MB is a 63 A C-curve; the 5SL4363-7 is a different variant. Check the specific rating and curve of the original spec — if it matches 63 A C-curve, the physical swap is direct without rewiring.
