At 240 V it interrupts up to 220 kA; at 415 V that drops to 154 kA, at 440 V to 75.6 kA, at 500 V to 30 kA, and at 690 V to 4.5 kA — the full range matters when the available fault current at the panel is known. At 55 °C the rating drops to 194 A, at 60 °C to 188 A, at 65 °C to 182 A, and at 70 °C to 176 A. Dimensions are 105 mm wide, 158 mm high, and 70 mm deep — a standard 3-pole MCCB footprint for a SENTRON 3VA frame. It ships with two auxiliary switches (HP design) factory-installed, so you get status feedback without adding a separate accessory block.","metaTitle":"Siemens SENTRON 3VA1220-6MH32-0AB0 MCCB, 200 A, 3-Pole, 70 m","metaDescription":"Siemens SENTRON 3VA1220-6MH32-0AB0 molded case circuit breaker, 200 A, 3-pole, 70 mm depth.
