That derating curve means if your panel runs hot, you still have a solid 91 A available at the top of the operating range. The interrupting ratings are what make this breaker stand out on a high-fault panel: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. For a buyer filling a BOM line, the key fit check is the 100 A rating at your panel's ambient temperature and the interrupting capacity your fault study calls for at the system voltage. If those match, this is a drop-in replacement for any panel designed around a 3-pole SENTRON 3VA frame. The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that fits SENTRON 3VA mounting hardware and busbar systems. Power loss is 27.5 W maximum, which matters for thermal calculations inside a sealed enclosure. If you're stacking several of these on a bus, that heat adds up — factor it into your ventilation or derating.","metaTitle":"3VA1110-5ED32-0DC0 SENTRON MCCB, 100A 3-Pole, 187kA at 240V","metaDescription":"Siemens SENTRON 3VA1110-5ED32-0DC0 molded case circuit breaker, 100A rated at 40°C, 3-pole, 187kA interrupting at 240V.
