Siemens 3VA1163-3GF46-0AA0 — 63 A SENTRON MCCB, 4-Pole, TM240 Release
Rated breaking capacity reaches 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V — the interrupting capability drops sharply above 440 V, so verify the available fault current at the installation voltage. Continuous current holds at 63 A from 40 °C through 50 °C ambient, then derates to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. For a panel running at 55 °C ambient, the breaker is good for 62 A — a 1 A reduction that matters for a fully loaded feeder.
Insulation voltage rated at 800 V. The breaker carries no communication function, no trip indicator, and no other measurement function — it is a pure overcurrent protection device.
