Breaking capacity stands at 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V, then drops to 17 kA at 500 V and 690 V — the high interrupt rating at the lower voltages makes this part suited for high-fault-capacity panelboards and transformer secondaries where the available fault current exceeds standard 65 kA or 100 kA MCCBs. The 3VA1120-6EF36-0AA0 occupies a 76.2 mm width, 130 mm height, and 70 mm depth — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount bases in the SENTRON family. No undervoltage release or communication function is built in, so any shunt trip or auxiliary contact must be added as a separate accessory. The 12 W maximum power loss is moderate for a 20 A frame; account for it in the enclosure thermal calculation if the panel is densely populated.","metaTitle":"Siemens SENTRON 3VA1120-6EF36-0AA0 MCCB, 20 A, 3-Pole, 220 k","metaDescription":"Siemens SENTRON 3VA1120-6EF36-0AA0 molded case circuit breaker, 20 A, 3-pole, 220 kA breaking capacity at 240 V.
