SENTRON 5SL4104-7 — 1-pole C-curve MCB, 4 A, 10 kA
Rated for 230/400 V AC single-phase / multi-phase operation, it fits standard DIN-rail enclosures at 18 mm width (1 modular unit) and 76 mm depth — a clean swap into any panel with a 1P slot.
Ratings and thermal derating
At 30 °C ambient the breaker carries 4 A; at 40 °C it derates to 3.79 A, at 45 °C to 3.68 A, and at 55 °C to 3.45 A. Plan your load margin against the cabinet's internal temperature rise — the 4 A nameplate holds only up to 30 °C.
Installation and accessories
Sealable, halogen-free, silicon-free — suitable for clean-room or food-grade panels where outgassing matters.
