Siemens SENTRON 3VA2110-7HK42-0AA0 — 100 A, 4-Pole MCCB with ETU340 Release
The interrupting capacity peaks at 330 kA at 240 V, dropping to 242 kA at 415 V and 440 V, then 187 kA at 500 V. At 690 V it still clears 3.7 kA — that covers most low-voltage fault scenarios in a plant distribution panel. The overcurrent release is an ETU340 electronic trip unit, adjustable for N-conductor protection (OFF, 50%, 100%). Front protection is IP40, so it keeps tools and fingers out but isn't sealed against washdown.
Maximum power loss is 10 W. Insulation voltage rated at 800 V.
Integration Notes
No auxiliary contacts or shunt trip are included — order those separately if needed. The ETU340 release is field-adjustable for N-conductor protection; the rotary dial sets the neutral pole to OFF, 50%, or 100% of the phase rating. No trip indicator, so fault diagnosis relies on the breaker's handle position.
