The 3VM1120-3ED22-0AA0 measures 70 mm deep, 50.8 mm wide, and 130 mm tall. That 2-inch width means it occupies a single 2-pole space in a standard Siemens panelboard or MCC bucket. Depth of 70 mm (2.76 in) leaves clearance for wiring gutters in most 8-inch-deep enclosures. The breaker holds 20 A continuously from 40 °C through 55 °C ambient. Maximum power loss is 8 W per pole.","metaTitle":"Siemens 3VM1120-3ED22-0AA0 SENTRON MCCB, 2-Pole, 20 A, 76 kA","metaDescription":"Siemens SENTRON 3VM1120-3ED22-0AA0 molded case circuit breaker, 2-pole, 20 A rated, 76 kA breaking capacity at 240 V AC.
