SENTRON 3VA1110-3ED46-0AA0 — MCCB for Line Protection
The Siemens 3VA1110-3ED46-0AA0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection, carrying a continuous current rating of 100 A at 40 °C with no derating needed up to 50 °C — above that it drops to 98 A at 55 °C and 91 A at 70 °C, so if your panel ambient runs hot, that's the number to size against. Interrupting capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, and 11.9 kA at 690 V, which covers most industrial service-entrance and distribution panel fault duties.
If you're freezing a BOM or managing a long-term project, the SENTRON 3VA platform is Siemens' main MCCB family, so replacement parts and accessories (auxiliary contacts, shunt trips, rotary handles) are standard catalog items. No second-source cross-reference needed — this is the primary line.
Physical Fit & Panel Integration
Dimensions: 130 mm tall, 101.6 mm wide, 70 mm deep — a 4-pole MCCB footprint that fits standard Siemens SENTRON mounting plates and panel cutouts.
