Siemens SENTRON 3VA1110-5EF32-0JA0 — 100 A MCCB with Shunt Trip
At 55 °C it drops to 96 A, at 70 °C to 90 A, so if your panel ambient sits above 50 °C, size the breaker for the actual load at temperature. If you need field-adjustable ampacity, look at the electronic-trip variants in the 3VA family. Front protection is IP40 — fine for a closed panel, but not rated for dust or hose-down. The shunt trip (STL) allows an E-stop or PLC to open the breaker remotely; no undervoltage release or auxiliary contacts are fitted on this order code.
Panel and Integration Notes
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — standard 3-pole MCCB footprint for DIN-rail or base-mount installation in a SENTRON distribution board or separate enclosure. The shunt trip coil (order code 3VA9688-0BL32) is integrated; verify control voltage matches your system before wiring.
