The Siemens SENTRON 3VA2010-5HN32-0DC0 is a 3-pole molded case circuit breaker rated for 100 A continuous at ambient temperatures up to 70 °C, with an interrupting capacity of 187 kA at 240 V and 121 kA at 415 V.
Ratings that govern fit
That means the breaker delivers its full continuous current even in a hot panel or outdoor enclosure, as long as ambient stays at or below 70 °C.
Panel integration
Dimensions are 86 mm depth, 105 mm width, 181 mm height. The 3-pole footprint matches standard SENTRON 3VA fixed-thermal-magnetic breakers, so it swaps into an existing 3VA lineup without re-drilling the gland plate.
