The Siemens SENTRON 3VA1112-3EE46-0AA0 is a 4-pole molded case circuit breaker rated 125 A continuous at 45 °C and 50 °C, derating to 114 A at 70 °C — so the thermal curve starts pulling back above 55 °C, which matters if this lands in a non-ventilated enclosure next to other heat sources. Breaking capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — that covers most North American and European distribution panels, but at 500 V and 690 V it drops to 11.9 kA, so verify the available fault current at the point of installation if you're feeding a 690 V drive.
The 4-pole format handles three-phase plus neutral switching, common for European-style TN-S or TN-C-S systems where the neutral needs isolation. Max power loss of 28.1 W at full load should be factored into enclosure thermal calculations.
