The overload protection Ir is adjustable from 14 A to 20 A, and the short-circuit protection Ii is fixed at 16 x In (320 A). This variant is designated for DC Power OEM in China, meaning the packaging and any accompanying documentation are tailored for that market. The breaker itself is a standard 3VA1 IEC device, so its electrical ratings and footprint are identical to the global version.","metaTitle":"Siemens 3VA1120-4EE42-0AA0-ZD00 3VA1 IEC Frame 160 Breaker,","metaDescription":"Siemens 3VA1120-4EE42-0AA0-ZD00 circuit breaker, 3VA1 IEC frame 160, breaking capacity class S, Icu=36kA @ 415V, 4-pole, In=20A, TM220 overload protection.
