The 2-pole construction (2 width units on a DIN rail) switches both phase and neutral in single-phase circuits, or two phases in a split-phase or two-leg three-phase tap. Rated insulation voltage is 440 V AC, with overvoltage category 3 — suitable for fixed-installation panels where transient overvoltages are controlled by upstream SPDs. ## Deployment context Ambient temperature range -20 to +45 °C covers most indoor plant-floor conditions; periodic excursions to +55 °C at 95% humidity are allowed but not continuous. Terminals accept solid or stranded conductors from 0.75 mm² up to 25 mm² — covers everything from 1.5 mm² lighting circuits to 16 mm² feeder tails. The sealable design (padlockable toggle) lets you lock the breaker in the OFF position for lockout/tagout, which is a practical requirement on maintenance-disconnect circuits. ## Mechanical endurance and vibration Rated for 20 000 mechanical switching cycles typical — that's the handle life, not the electrical endurance at full rated current (which will be lower). Vibration resistance tested to 50 m/s² at 25–150 Hz and 60 m/s² at 10–150 Hz per IEC 60068-2-6, so it holds up on machinery panels near rotating equipment or conveyors.","metaTitle":"Siemens 5SJ6216-6 SENTRON MCB, 2-Pole B 16A 6kA 400V","metaDescription":"Siemens 5SJ6216-6 SENTRON miniature circuit breaker, 2-pole, B-curve, 16 A, 6 kA breaking capacity per EN 60898 at 400 V AC.

The only difference is the 16 A rating vs 20 A.
