Its interrupting capacity reaches 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V — figures that govern fault-clearing capability in high-fault panels. No auxiliary contact version is fitted as standard.
The 25 A rating holds at ambient temperatures up to 50 °C; above that it derates to 24 A at 55 °C, 23.5 A at 60 °C, 23 A at 65 °C, and 22.5 A at 70 °C. No communication function, phase failure detection, or ground fault monitoring is built in.
75.6 kA at 415 V, with 121 kA at 240 V and 52.5 kA at 440 V.
