Its interrupting capacity hits 187 kA at 240 V and 121 kA at 415 V and 440 V — numbers that tell you it handles high-fault utility feeds or transformer secondaries without cascading upstream.
Thermal derating — the real-world current limit
Above that it derates linearly: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. The maximum power loss of 48 W also factors into the enclosure thermal budget.
Auxiliaries and communication built in
The communication function means it can report status and accept remote trip commands over the bus — useful for a BMS or SCADA-connected distribution board.
