What this 250 A SENTRON MCCB does on the line
It carries a 187 kA interrupting capacity at 240 V AC, which drops to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 4.5 kA at 690 V — so the SCCR headroom is substantial on 480 V or 600 V class systems, but verify the available fault current at your specific voltage.
Sizing and thermal derating for panel builders
Above that, it derates linearly: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C.
Auxiliary configuration and what ships with the breaker
No ground-fault monitoring module is included — that would be a separate add-on. No communication function is built in; status is available only through the hardwired auxiliary contacts.
