The Siemens SENTRON 3VA2010-5HL32-0AF0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, with a breaking capacity of 187 kA at 240 V AC and 121 kA at 415/440 V — enough to handle high-fault industrial feeders without cascading upstream. It includes a factory-fitted auxiliary switch plus a separate trip-alarm switch (1 AUX + 1 ALARM HQ), so you get remote status and fault indication without adding an accessory later.
Three-pole design suits three-phase line protection for feeders, motor branch circuits, or main incomers in industrial switchboards.
