Siemens 3VA1010-4ED42-0KC0 — 100 A SENTRON MCCB for Line Protection
Interrupting capacity is the headline: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. Current rating holds flat at 100 A through 50 °C, then derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C.
The 101.6 mm width (4-inch footprint) is standard for a 4-pole MCCB in this class — drops into existing SENTRON or comparable panel layouts without re-drilling the mounting plate. Two auxiliary switches (HQ type) are integrated, giving status feedback for the open/closed position. The shunt trip (STL) release allows remote tripping — wired to an E-stop or PLC output, it drops the breaker without a manual handle pull. The 15 000 latching endurance cycles suit frequent-switching applications like compressor or pump panels, not just infrequent fault protection.
