SENTRON 5SY8601-7 — 1 A C-curve MCB, 4-pole, 70 kA
It is a 4-pole unit (3P+N) with neutral conductor switching, designed for AC circuits up to 440 V single- or multi-phase. The breaking capacity is 70 kA per IEC 60947-2, with a DC rating of 15 kA at up to 72 V.
The 15 kA DC rating at 72 V extends its use to DC control circuits, though the primary application is AC. Temperature derating is specified: 1 A at 45 °C, 0.98 A at 50 °C, 0.95 A at 55 °C. In a warm panel (e.g., near 50 °C), the effective continuous current drops to 0.98 A — factor this into load planning. The 4-pole design with neutral switching (3P+N) means the neutral is switched and protected, not just a solid link — required in some IEC installations for single-phase loads on a three-phase system.
Sealable, halogen-free, silicon-free — relevant for clean-room or food-bev environments where outgassing must be controlled.
The product designation follows EN 61346-2 and IEC 81346-2 (function code F). Suitability for mechanical engineering and industry is stated.
