At 40 °C the continuous rating derates to 1.9 A, and at 55 °C to 1.75 A — factor that into panel thermal calculations if the breaker shares a crowded enclosure. For DC applications the maximum rated voltage is 72 V — verify polarity and arc extinction if using in a DC subpanel. Depth behind the panel is 70 mm; overall depth 76 mm. The 72 mm width (4 MW) matches the standard 18 mm/module grid — no special end plates or adapters needed for a typical distribution board. Touch protection is built in (fingertip-safe terminals when wired). Sealable with a lead or tag for tamper-evident installations. Mechanical endurance is 10,000 switching cycles typical, which is adequate for branch-circuit protection where the breaker is operated infrequently. The neutral conductor is not switched on this 4-pole breaker (3 poles + solid neutral). Confirm the system grounding scheme before specifying — if a switched neutral is required, a different variant in the 5SL series would be needed.","metaTitle":"Siemens 5SL6402-7 SENTRON MCB, 4P C 2A 6kA 400V","metaDescription":"Siemens SENTRON 5SL6402-7 miniature circuit breaker, 4-pole, C-curve, 2A rated, 6kA breaking capacity per IEC 60898/60947-2, 400V AC.
