The Siemens 3VA2463-5JP32-0AG0 is a 3-pole SENTRON molded case circuit breaker rated for 630 A continuous current at 40 °C, with a maximum breaking capacity of 187 kA at 240 V and 121 kA at 415 V. The trip indicator gives a clear visual signal after a fault event, speeding up fault isolation on the floor.
Breaking capacity drops as system voltage rises: 187 kA at 240 V, 121 kA at both 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. The minimum breaking current is 945 A, so it will clear low-level faults down to that threshold.
The 630 A rating holds only at 40 °C ambient. Above that, derate linearly: 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. Maximum power loss is 162 W.
