Siemens 5SL4615-7 SENTRON MCB — 1.6 A, C-Curve, 3P+N, 400 V, 10 kA
The Siemens 5SL4615-7 is a SENTRON miniature circuit breaker rated 400 V AC with a 10 kA breaking capacity certified to both EN 60898 and IEC 60947-2. It carries a C tripping characteristic at 1.6 A in a 3P+N (4-pole) configuration, occupying 4 modular width units on a DIN rail.
Mounting position is unrestricted — horizontal, vertical, or flat. The IP20 finger-safe enclosure applies only with connected conductors; terminals are live when open. The 3P+N design switches the neutral pole as well — not just a solid link. That matters for TN-S or TT systems where you need guaranteed isolation on all live conductors during maintenance. Sealable housing (provision for a lead seal or lockout) and halogen-free / silicon-free construction, so it's suitable for environments where outgassing from a fault could contaminate nearby electronics or where compliance with low-smoke material specs is required.
Overvoltage category III (fixed installation, not plug-in), pollution degree 2 (non-conductive dust only), energy limitation class 3 — all standard for a DIN-rail MCB in a distribution board.
Electrical and mechanical ratings
Rated for AC operation at 400/440 V, 50/60 Hz. DC rating is 72 V maximum — usable for DC branch circuits but only up to that voltage.
