What this MCCB carries and where it fits
The Siemens 3VA1110-3ED32-0AA0 is a 3-pole SENTRON molded case circuit breaker rated for line protection, with a TM210 thermal-magnetic release. At 40 °C it carries 100 A continuous — the rating holds through 50 °C, then derates to 98 A at 55 °C and 91 A at 70 °C. Interrupting capacity reaches 75.6 kA at 240 V, dropping to 52.5 kA at 415 V and 32 kA at 440 V; at 690 V it still clears 11.9 kA. The 70 mm depth and 76.2 mm width fit standard panel cutouts, and the front face carries IP40 protection.
Integration brief — panel fit and thermal derating
Mounts on DIN rail or direct panel; the 70 mm depth leaves clearance for standard gland plates. The TM210 release is fixed — no interchangeable trip units, so the 100 A rating is the only frame size. For ambient above 50 °C, follow the derating curve: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, 91 A at 70 °C. Maximum power loss is 25 W; ensure ventilation in crowded enclosures.
