Breaking capacity is the real differentiator here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V or 690 V. At 415 V the 121 kA still covers most industrial panelboards. Sourcing is straightforward: we quote it against an RFQ. Volume pricing drops with quantity — typical for the SENTRON family. If you need a motor drive option, the product extension supports it (optional accessory). Dimensions are 70 mm deep, 101.6 mm wide, 130 mm tall — a 4-pole MCCB that fits standard DIN-rail or panel-mount enclosures. The 101.6 mm width (4 inches) is the pole pitch for a 4-pole device; check your enclosure's mounting plate for the bolt pattern. Maximum power loss is 12 W, so ventilation in a sealed cabinet should account for that heat. The IP40 front face means no gasket sealing — fine for a clean panel, but not for dusty or wet locations.","metaTitle":"Siemens 3VA1120-5ED46-0AA0 SENTRON MCCB, 4-pole, 20 A, 187 k","metaDescription":"Siemens SENTRON 3VA1120-5ED46-0AA0 molded case circuit breaker, 4-pole, 20 A rated, 187 kA breaking capacity at 240 V.
