The C-curve holds through momentary inrush up to 10× rated current before the magnetic trip fires, so it won't nuisance-trip on a motor start or a capacitor bank energisation. The 1-pole form factor is for single-phase branch circuits; if you need two-pole protection for a 400 V line-to-line load, the 5SJ6220-6 (20 A, B-curve) or 5SJ6216-6 (16 A, B-curve) share the same 70 mm depth and wire range, but swap the pole count and curve. Installation depth is 70 mm, which matches the standard SENTRON enclosure depth — no extra clearance needed behind the panel door. The terminals accept solid or stranded conductors from 0.75 mm² up to 25 mm², covering everything from 1.5 mm² lighting circuits to 10 mm² feeder tails. The IP20 rating (with conductors connected) is typical for enclosed distribution boards; the breaker itself is touch-protected per the product feature.","metaTitle":"Siemens 5SJ6150-7 SENTRON MCB, 1-Pole C 50A 6kA","metaDescription":"Siemens 5SJ6150-7 SENTRON miniature circuit breaker, 1-pole, C-curve, 50 A, 6 kA per EN 60898.
