Breaking capacity across voltages
Interrupting capacity drops as system voltage rises: 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V.
Current rating holds at 25 A from 40 °C through 50 °C, then steps down to 24 A at 55–60 °C and 23 A at 65–70 °C. The 70 mm depth and 76.2 mm width (3-inch standard) fit a typical MCCB slot on a DIN rail or panel-mount base; the 130 mm height leaves room for auxiliary switch wiring above. Maximum power loss is 8.5 W — negligible for enclosure thermal calculations but worth noting in sealed cabinets.
