Rated at 25 A continuously at 40 °C, it holds that full rating through 50 °C, then derates to 24 A at 55–60 °C and 23 A at 65–70 °C — useful to know if the panel runs hot near a drive or transformer.
Interrupting capacity — voltage-dependent, not a single number
The 76 kA at 240 V is the headline figure, but the real-world SCCR drops sharply as system voltage rises: 53 kA at 415 V, 32 kA at 440 V, and 8 kA at 500 V. Rated insulation voltage Ui is 690 V, and max DC operational voltage is 500 V.
Lifecycle stage is marked as current — meaning Siemens still lists it as an active catalog number with no announced end-of-life or last-time-buy window.
No communication function, no motor drive option, no neutral conductor upgrade path. The 3-pole width is the standard 3-inch (76.2 mm) MCCB footprint — drops into a panel lugged for a 3-pole SENTRON frame without re-drilling the mounting plate.
