Rated breaking capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC, giving headroom for most commercial and light industrial panel applications without needing upstream current-limiting fuses. Occupies 2 modular width units (36 mm) on standard DIN rail, with a depth of 70 mm — fits the common 4-module-per-inch footprint used across European panel layouts. ## Breaking capacity and selectivity planning The dual-rated breaking capacity — 10 kA to EN 60898 and 15 kA to IEC 60947-2 — means this MCB can be specified under either standard. The IEC 60947-2 figure is the one to use for industrial control panels where the standard requires performance coordination with upstream devices. Rated insulation voltage (Ui) is 440 V AC, and the overvoltage category is 3 with pollution degree 3 — suitable for fixed installations where transient overvoltages are expected, such as main distribution boards. The C-curve trips at 5 to 10 times rated current, which provides good selectivity with downstream B-curve MCBs on lighting circuits while still clearing moderate overloads on motor feeders. ## Sourcing and lifecycle status The 5SJ4210-7HG41 is a current-catalog item within the SENTRON 5SJ4 series. No official successor or replacement has been announced, and the design is stable for ongoing panel builds.","metaTitle":"Siemens 5SJ4210-7HG41 2-Pole MCB, C-Curve, 10 kA EN 60898","metaDescription":"Siemens 5SJ4210-7HG41 SENTRON 2-pole MCB, C characteristic, 10 kA per EN 60898 / 15 kA per IEC 60947-2.
