The Siemens SENTRON 3VA1110-5ED32-0AG0 is a 3-pole molded case circuit breaker rated for 100 A continuous at 40 °C, with a TM210 thermal-magnetic release for line protection. It carries a 187 kA interrupting capacity at 240 V, dropping to 121 kA at 415 V and 75.6 kA at 440 V — enough headroom for most industrial service-entrance or feeder duty where fault currents run high.
Compared to the 3VA1110-5ED32-0AA0 — which shares the same frame and TM210 release — the -0AG0 adds a factory-installed auxiliary switch (1 N/O + 1 N/C) and a separate trip-alarm switch. If your BOM calls for remote status feedback without wiring an external accessory block, the -0AG0 saves a DIN slot and the labor to fit it. The -0AA0 is the bare breaker; this one ships ready for indication.
Mounts on DIN rail (76.2 mm wide, 130 mm tall, 70 mm deep) — standard panel footprint for a 100 A frame. The TM210 release is fixed thermal-magnetic, so no adjustment dial; you size the breaker to the load and leave it.
