SENTRON 5SQ2670-0KA13 — 4-pole MCB, panel-fit notes
Rated 13 A with a C-curve tripping characteristic, it interrupts faults up to 3 kA per EN 60898 at 400 V AC, 50 Hz.
At 13 A it protects a 3–4 kW resistive or mixed load on a 400 V three-phase system. The 3-pole-plus-neutral configuration means the neutral is switched and protected; use it where the neutral conductor must be disconnected on fault or isolation, common in IT or TN-S systems. Overvoltage category 3 and energy limiting class 3 mean this breaker limits let-through energy during a fault. The 3 width units leave room for adjacent devices in a multi-way board.
