The Siemens SENTRON 3VM1463-5EE42-0AA0 is a 4-pole molded case circuit breaker rated for 630 A continuous at 40 °C, with a TM220 thermal-magnetic release. No ground-fault monitoring or communication function is built in.
Current rating holds at 630 A from 40 °C through 50 °C, then derates linearly to 583 A at 70 °C. The 193 W maximum power loss should be factored into enclosure ventilation.
Dimensions: 248 mm height, 184 mm width, 110 mm depth. Rated insulation voltage Ui is 690 V AC; maximum DC operational voltage is 500 V. The neutral conductor is not integrated and cannot be retrofitted — external neutral bar required for 4-wire systems.
