Siemens SENTRON 3VA1110-3GE46-0AA0 — 100 A 4-Pole MCCB with TM220 Release
The 100 A rating holds at ambient temperatures up to 50 °C without derating; at 55 °C it carries 98 A, at 60 °C it carries 96 A, and at 70 °C it carries 91 A. For a panel with elevated internal temperatures — say, a packed enclosure near a mash-tun or steam line — the 55 °C derating curve is the one to size against, not the 40 °C headline. Breaking capacity varies by system voltage: 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. For a 400 V three-phase distribution panel feeding a brewery's motor control center, the 52.5 kA at 415 V figure is the one that governs SCCR coordination downstream.
Panel Fit and Mounting
This MCCB measures 70 mm deep, 101.6 mm wide, and 130 mm high — a standard SENTRON 3VA frame size that fits DIN-rail or screw-mount panel layouts. The 4-pole width (101.6 mm) matches the footprint of other 3VA 4-pole breakers, so a panel drilled for a 3VA1110-5ED32-0AA0 or similar 4-pole unit accepts this one without re-drilling or busbar rework.
