What this MCCB carries and where it fits
The Siemens SENTRON 3VA1110-5EE32-0HH0 is a 3-pole molded case circuit breaker rated for 100 A continuous current (Iu) with a TM220 thermal-magnetic overcurrent release. Its 187 kA interrupting capacity at 240 V AC makes it a high-fault unit for main or feeder duty in industrial distribution panels. At 415 V it still clears 121 kA, and at 690 V it holds 17 kA — so the SCCR you need for the line-side fault current decides the voltage tap you land it on. Rated insulation voltage is 800 V, and the breaker carries a shunt trip release (STL) plus 2 auxiliary switches and a separate trip alarm switch (HQ). That means you can remote-trip it from an E-stop string and get a dedicated alarm contact back to the PLC without stacking add-on blocks. The front face is IP40 — fine for a clean indoor panel; not rated for washdown. Current rating holds at 100 A up to 50 °C ambient, then derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. If the panel ambient runs above 50 °C, size the downstream load against the derated number, not the nameplate Iu.
Mounting and integration notes
Footprint is 76.2 mm wide, 130 mm tall, 70 mm deep — a standard 3-pole MCCB envelope that drops into most SENTRON panelboards and DIN-rail adapter plates without re-drilling. The 3VA9688-0BL30 integrated auxiliary trip is factory-fitted; verify the wiring diagram for the shunt trip polarity before energizing.
