Breaking capacity hits 187 kA at 240 VAC and 121 kA at 415 VAC, dropping to 3.7 kA at 690 VAC.
Trip range and selectivity
The adjustable thermal-magnetic trip covers 150 A to 1200 A, with the continuous rating locked at 100 A. That means the breaker itself is a 100 A frame, but the trip unit can be dialed to coordinate with downstream protection — useful for selectivity studies where you need a wider pickup band than the frame rating alone suggests. Compared to a fixed-trip MCCB of the same frame, the adjustable range lets you tune the instantaneous pickup without swapping the breaker. For a panel OEM wiring multiple feeds off the same bus, this cuts SKU count — one frame covers several tap ratings.
The 3VA2110-5JQ32-0DA0 measures 105 mm wide, 181 mm tall, and 86 mm deep — a 3-pole MCCB footprint that fits standard Siemens SENTRON mounting bases. Depth stays under 90 mm, so it clears shallow gland-plate enclosures. A communication function is onboard — expect Modbus or PROFIBUS capability via the SENTRON communication module, though the exact protocol depends on the plug-in accessory chosen. That's a space-saver in retrofit panels where neutral bar access is tight.
