Key Ratings and What They Mean for Your Panel
The 5SP5180-7: Rated 80 A at 400 V AC (50 Hz) and 250 V DC, this MCB handles high-current branch circuits in industrial control panels. The C-curve characteristic means it trips between 5 and 10 times rated current — appropriate for motor and transformer loads with moderate inrush, common in conveyor, pump, and compressor circuits. The 10 kA breaking capacity at DC per EN 60898-2, and 15 kA per IEC 60947-2, tells you it can safely interrupt a fault up to that level without welding contacts or cascading upstream. The 3 kA rating per EN 60898 at AC covers the standard residential/commercial short-circuit condition.
Mounting and Environmental Fit
Mounts on standard DIN rail or via screw fixing, in any position — useful when panel layout forces a non-vertical orientation. The 27 mm width (1.5 width units) fits SENTRON's modular grid; the 70 mm installation depth leaves clearance behind the DIN rail for wiring. Rated IP20 with connected conductors, so it belongs inside a closed panel, not in a washdown zone. Ambient range from -40 °C to 75 °C, with up to 95% humidity — takes the heat and cold of an unheated electrical room or a cabinet near process heat. Sealable, halogen-free, and silicon-free construction matters for environments where outgassing can corrode contacts or sensitive electronics.
