Interrupting capacity hits 100 kA at 240 V AC and 65 kA at 480 V AC, with a 25 kA rating at 600 Y/347 V — figures that cover most commercial and light industrial fault-current scenarios without needing a current-limiting upstream device. Full 20 A rating holds at 40 °C and 45 °C; derate to 19 A at 50 °C and 55 °C, 18 A at 60 °C and 65 °C, and 17 A at 70 °C — so a panel running warm near the top of a cabinet needs the 17 A figure for continuous load sizing. Width of 76.2 mm (3 in) and depth of 75.1 mm (2.96 in) mean it occupies a standard 3-pole MCCB footprint on the DIN rail or panel-mount plate; height of 129.4 mm (5.09 in) clears most 200 mm tall enclosures. Max power loss of 8.5 W is low enough that adjacent breakers in a multi-pole group don't need extra ventilation spacing under 40 °C ambient. IP40 front protection suits enclosed panel mounting; no ground-fault monitoring or undervoltage release built in, so those functions need external modules if required.","metaTitle":"SENTRON 3VA4120-6ED34-0AA0 Molded-Case Circuit Breaker, 20 A","metaDescription":"SENTRON 3VA4120-6ED34-0AA0 molded-case circuit breaker, 3-pole, 20 A, TM210 release, 100 kA at 240 V.
