At 415 V the 53 kA rating is the figure that governs most European industrial distribution panels. At 440 V it drops to 32 kA, and at 500 V to 12 kA — still enough for secondary distribution in a 480 V plant. The LI protection function (long-time and instantaneous) with an adjustable li max of 2000 A lets the site engineer coordinate downstream branch breakers without nuisance trips on motor inrush. Dimensions are 105 mm wide, 158 mm high, 70 mm deep. The 3-pole footprint matches the standard SENTRON 3VM family cutout. Rated insulation voltage Ui is 690 V AC; max DC operational voltage is 500 V.","metaTitle":"Siemens 3VM1220-3ED32-0AA0 SENTRON MCCB, 200 A, 3-Pole, 76 k","metaDescription":"Siemens SENTRON 3VM1220-3ED32-0AA0 molded case circuit breaker, 200 A at 40 °C, 3-pole, 76 kA at 240 V.
