Its interrupting capacity reaches 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — figures that cover high-fault utility and transformer-fed installations where SCCR headroom is a coordination requirement. The breaker measures 70 mm deep, 76.2 mm wide, and 130 mm high — a 3-pole footprint that fits standard SENTRON 3VA mounting bases and DIN-rail adapters without requiring panel rework from earlier 3VA1 frame sizes. Maximum power loss is 12 W, so thermal dissipation inside a sealed enclosure should be checked against the cabinet's heat budget.","metaTitle":"Siemens 3VA1120-6EF36-0KA0 SENTRON MCCB, 3-Pole, 20A, 220kA","metaDescription":"Siemens 3VA1120-6EF36-0KA0 SENTRON molded case circuit breaker, 3-pole, 20A rated, 220kA interrupting at 240V.
