The Siemens 3VA2110-5HN36-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated for line protection, with a continuous current of 100 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415/440 V, and 75.6 kA at 500 V, so it handles high-fault utility feeds and large motor branch circuits without cascading upstream.
Three-pole design, 105 mm wide, 181 mm tall, 86 mm deep — fits standard panel-mount cutouts for SENTRON 3VA fixed breakers. IP40 on the front protects against tool entry; suitable for enclosed distribution boards.
