Siemens SENTRON 3VA1220-4EF32-0KH0 — 200 A MCCB, Line Protection, Active Production
The 200 A rating holds from 40 °C through 50 °C ambient, then derates linearly to 176 A at 70 °C. Breaking capacity varies with system voltage: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V. This covers most low-voltage distribution panels; the 690 V figure is notably lower, so verify fault current at that level.
The trip indicator and voltage trigger are present, and the auxiliary switch configuration (2 aux + 1 trip alarm) is built in — no separate add-on module needed for basic signaling.
