At 55 °C it derates to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A. For a panel builder or site engineer sizing a motor branch in a warm enclosure, that means you can still pull the full motor FLA (up to 100 A) through the breaker as long as the ambient inside the panel stays at or below 50 °C — no need to oversize the frame. Above 50 °C, the derating curve is shallow enough (roughly 0.4 A per °C) that you can still land a 90 A motor load at 70 °C without bumping to the next frame. The 3VA1110-6MH36-0DD0 measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a compact 3-pole MCCB footprint that fits standard 3-inch-wide panel gutters. Mounting is via the SENTRON 3VA common backplate or DIN rail adapter (not included). For a retrofit into an existing panel that was built around a 3VA1110-5ED36-0AC0, the dimensions are identical — same depth, width, and height — so no rewiring or re-drilling is needed; it drops into the same mounting hole pattern and bus bar connection points. ## Starter protection design and auxiliary releases This breaker's design is explicitly for starter protection — it has a magnetic-only or thermal-magnetic trip curve optimized to ride through motor inrush (typically 6–8x FLA for a few cycles) while still providing short-circuit protection for the contactor and overload relay downstream. The UVR is wired separately from the main power path. The breaker also comes with three auxiliary switches (HQ design) for remote status indication. The basic switch element is order code 3VA11106MH360AA0.","metaTitle":"Siemens 3VA1110-6MH36-0DD0 SENTRON MCCB, 100A, 220 kA at 240","metaDescription":"Siemens SENTRON 3VA1110-6MH36-0DD0 molded case circuit breaker, 100A rated, 220 kA breaking capacity at 240V AC. 3-pole, starter protection design with undervoltage release.
