The 220 kA at 240 V is the headline number for high-fault service-entrance or distribution panels where the available fault current is substantial; the 17 kA at 690 V tells you this breaker is not intended for 690 V motor circuits unless the upstream transformer limits fault current to that level. Current rating holds at 20 A from 40 °C through 55 °C, then derates to 19 A at 60 °C and 65 °C, and stays at 19 A at 70 °C. That flat derating curve means the breaker can be installed in a warm enclosure without losing ampacity until the ambient passes 55 °C — useful for panels packed near other heat sources. The 3VA1120-6EF36-0DH0 measures 130 mm high, 76.2 mm wide, and 70 mm deep.","metaTitle":"Siemens 3VA1120-6EF36-0DH0 SENTRON MCCB, 20 A, 3-Pole, 220 k","metaDescription":"Siemens SENTRON 3VA1120-6EF36-0DH0 molded case circuit breaker, 20 A rated, 3-pole, 220 kA breaking capacity at 240 VAC.
