SENTRON 5SY6315-7 — 3-pole MCB, C-curve, dual-rated breaking capacity
At DC, it is rated 15 kA per IEC 60947-2, covering 60 V (max 72 V) control circuits. Rated for 400 V AC (440 V max) and 60 V DC.
Breaking capacity and standards — what the dual rating means for your panel
The 6 kA rating under EN 60898-1 is the standard for final circuits in buildings. The 30 kA under IEC 60947-2 is the industrial rating — this is the figure that matters for SCCR coordination in a machine panel or industrial switchboard. A UL 1077 listing at 5 kA (AC) covers North American supplementary-protector applications. The dual rating means this single part number can serve both a European distribution board (EN 60898) and an industrial machine (IEC 60947-2) without a separate high-fault variant. Compared to the 5SY6332-7CC (a 2-pole, higher-current variant), the 5SY6315-7 is the 3-pole choice for three-phase loads.
Lifecycle and sourcing — active production, quoted to order
Compliance documentation is available: the part carries IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 approvals.
Mounting and integration — DIN-rail, any position, sealable
Mounting position is unrestricted — horizontal, vertical, or inverted — which simplifies panel layout when busbar routing forces an unconventional orientation. The sealable design (padlockable toggle) allows lockout/tagout without an external lockout hasp.
