Its 250 A continuous rating at 40 °C means it carries that load without derating up to 50 °C — above that, the thermal curve drops to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. That derating profile is what you size against actual panel ambient, not the nameplate. The breaking capacity tells you where it clears faults without upstream coordination: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. The 1 auxiliary switch plus 1 trip alarm switch HP gives you remote status and fault indication — useful for PLC-based monitoring without adding a separate alarm module.
Mounts in a standard distribution panel — the 86 mm depth and 140 mm width fit typical Siemens SENTRON mounting bases. The trip indicator gives a visual flag on the breaker face, so a walk-through inspection catches a tripped unit without opening the panel door.
