The D characteristic's magnetic trip threshold is 10 to 20 times In (800 to 1600 A), so it holds through a motor's locked-rotor surge but opens on a bolted fault. The 1.5 modular width units (27 mm wide) take up one and a half standard DIN-rail spaces; check your enclosure's busbar pitch if you're retrofitting into an existing distribution block. Rated for -40 °C to 75 °C ambient, so it works in unheated warehouses or hot cabinet summers. The 10 000 mechanical operating cycles cover years of occasional switching — not a daily disconnect switch, but fine for a feeder breaker. Shock resistance of 150 m/s² at 11 ms half-sine and vibration resistance of 50 m/s² at 25–150 Hz mean it survives shipping and machine vibration without false trips.","metaTitle":"Siemens 5SP4180-8 SENTRON MCB, 1P D 80 A 10 kA","metaDescription":"Siemens SENTRON 5SP4180-8 miniature circuit breaker, 1-pole, D-curve, 80 A, 10 kA per IEC 60898, 400 V AC.
