Panel cutout and enclosure planning: depth 76 mm (70 mm installation depth behind the panel), width 36 mm (2 MW), height 90 mm. IP20 with connected conductors — this is a panel-internal device, not for wet or outdoor locations without an enclosure. Mechanical endurance 10,000 operating cycles typical. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Sealable design allows lockout/tagout with a padlock hasp.","metaTitle":"Siemens 5SY6540-7CC SENTRON MCB, C-Curve 6kA, 1P+N","metaDescription":"Siemens 5SY6540-7CC SENTRON miniature circuit breaker, C characteristic, 6 kA per EN 60898, 1P+N, 2 MW, active production.

The 5SY6540-7CC is 1P+N with 6 kA; the 5SY4116-7CV is a 1-pole variant at a lower rating. Panel rewiring would be needed if the neutral-switching pole is required — the 5SY4116-7CV does not switch neutral. Verify the BOM requirement before substituting."},{"question":"What compliance documentation does Siemens provide for 5SY6540-7CC?","answer":"The breaker is rated per EN 60898 (6 kA) and UL 1077 / CSA C22.2 No.235 (5 kA). It is halogen-free and silicon-free. Standard documentation includes the manufacturer's declaration of conformity (CE/UKCA) and material compliance statements available on request."},{"question":"Where can I buy 5SY6540-7CC and how is it quoted?","answer":"The 5SY6540-7CC is sourced to order against an RFQ.
