The TM120M release provides thermal protection for overloads and magnetic protection for short circuits, tuned for motor and starter duty where inrush currents must be tolerated without nuisance tripping. ## Current Derating and Thermal Performance The 3VA1110-6MH32-0KA0 holds its full 100 A rating from 40 °C through 50 °C ambient, then derates to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C — important for panels with high internal heat rise or adjacent heat-generating equipment. The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole MCCB footprint that fits standard SENTRON mounting patterns and busbar systems.","metaTitle":"Siemens 3VA1110-6MH32-0KA0 SENTRON MCCB, 100 A, 220 kA at 24","metaDescription":"Siemens SENTRON 3VA1110-6MH32-0KA0 molded case circuit breaker, 3-pole, 100 A rated continuous current, 220 kA breaking capacity at 240 V.
