That thermal curve matters when you're packing breakers side-by-side in a distribution board; the 12 W maximum power loss per unit adds up in a dense enclosure. Breaking capacity is the headline: 53 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500 V. The 690 V rated insulation voltage (Ui) confirms it's built for 400/480 VAC systems with headroom. Dimensions: 70 mm deep, 101.6 mm wide, 130 mm high. 101.6 mm width (4 inches) is the standard 4-pole MCCB footprint. IP40 on the front. Mechanical endurance rated at 10,000 operations.","metaTitle":"Siemens 3VM1020-2ED42-0AA0 SENTRON MCCB, 20 A, 4-Pole, 53 kA","metaDescription":"Siemens SENTRON 3VM1020-2ED42-0AA0 molded case circuit breaker, 20 A rated, 4-pole, TM210 release.
