Breaking capacity across voltages
The 3VA2110-6HN32-0KH0: Breaking capacity drops from 242 kA at 240 V to 187 kA at 415 V and 440 V, then to 121 kA at 500 V, and 5 kA at 690 V. For a 400 V panel, that 187 kA figure covers most industrial service-entrance duty.
Thermal derating and release
Rated 100 A up to 50 °C; above that, derate linearly to 85 A at 70 °C. The ETU350 electronic overcurrent release handles LSIG curves — adjust the trip thresholds to coordinate with downstream breakers. An integrated shunt trip (STL) and two auxiliary switches plus a trip-alarm switch come factory-fitted, so no separate wiring for remote signaling.
Mounting and environment
Dimensions 86 mm deep × 105 mm wide × 181 mm high — fits standard SENTRON panel cutouts. Operating range -25 °C to 70 °C, storage -40 °C to 80 °C. Maximum power loss 10 W; plan for ventilation in a sealed enclosure.
