Rated for 50 Hz AC only, with a maximum operating voltage of 440 V in multi-phase operation. Three poles (3P, no switched neutral) suit a three-phase load or a three-phase supply with separate neutral bar. Ambient temperature range -40 to +75 °C, with periodic +55 °C / 95% humidity influence noted. Mount in any position, installation depth 70 mm. ## Panel integration and compliance Snap-on mounting for standard DIN-rail enclosures. 3 width units (54 mm wide) fit a 3-pole breaker in a cutout row. Touch protection is integral. Pollution degree 2, overvoltage category III — the usual spec for fixed-installation switchgear. Sealable (yes) allows lockout/tagout on the toggle.","metaTitle":"Siemens 5SN6310-8CN SENTRON MCB, 3P D 10A 6kA 400V","metaDescription":"Siemens SENTRON 5SN6310-8CN miniature circuit breaker, 3-pole, D-curve, 10 A, 6 kA breaking capacity at 400 V AC.
