For a 415 V distribution panel, that puts it in the high-capacity class (class H in Siemens' own grading), suitable for installations with high prospective fault current — think industrial switchboards close to a transformer or a large motor control center. The overload protection is adjustable from 18 A to 25 A (Ir), and the short-circuit pickup (Ii) is set between 6.4 and 12.8 times In — so at the 25 A setting, that's 160 A to 320 A magnetic trip. That range lets you coordinate with downstream branch breakers or motor starters.","metaTitle":"Siemens 3VA1125-6EF42-0AA0-ZD00 Circuit Breaker, 70kA @ 415V","metaDescription":"Siemens 3VA1125-6EF42-0AA0-ZD00 circuit breaker, IEC frame 160, 70kA breaking capacity @ 415V, 25A, TM240.
