Thermal derating is minimal up to 50 °C (full 200 A), then drops to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C — a 12% reduction at the top end, which matters for enclosed panels with limited ventilation. ## Auxiliary Configuration and Release Options Footprint is 105 mm wide by 158 mm tall by 70 mm deep — a standard SENTRON 3VA12 frame size that fits existing 3VA panel cutouts and busbar systems without modification.","metaTitle":"Siemens 3VA1220-5MH32-0KH0 SENTRON MCCB, 200 A, 3-Pole","metaDescription":"Siemens 3VA1220-5MH32-0KH0 SENTRON molded case circuit breaker, 200 A rated, 3-pole, 187 kA at 240 V.
