The Siemens SENTRON 3VA1010-3ED36-0AH0 is a 3-pole molded case circuit breaker (MCCB) for line protection, rated 100 A at 40 °C and carrying a 75.6 kA interrupting capacity at 240 V.
Current derating and thermal limits
Above that it derates: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, 91 A at 70 °C. In a sealed, uncooled enclosure that hits 60 °C ambient, figure 96 A continuous — not 100 A.
Interrupting ratings across voltages
The 75.6 kA at 240 V drops to 52.5 kA at 415 V, then 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V.
Width 76.2 mm (3 in), height 130 mm (5.12 in), depth 70 mm (2.76 in). Three-pole MCCB in a standard 3-inch-wide footprint — fits most DIN-rail or panel-mount SENTRON bases. Verify the mounting base (3VA10103ED360AA0 is the supplied basic switch) and whether the auxiliary switch block adds depth beyond the 70 mm.
