The Siemens SENTRON 3VA2110-5HN36-0AC0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, designed for line protection in distribution panels. Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — so it handles high-fault scenarios on the low-voltage side while still clearing moderate faults at higher voltages.
Sizing and thermal performance
The 100 A rating holds flat from 40 °C all the way to 70 °C ambient — no derating needed in a warm enclosure, which is unusual for an MCCB this size. Maximum power loss is 10 W, so it won't cook neighboring components in a dense panel.
Dimensions are 181 mm high, 105 mm wide, 86 mm deep — standard MCCB footprint for a 100 A frame, mounts on a DIN rail or direct panel.
