The thermal-magnetic trip offers adjustable overload protection from 175 A to 250 A and fixed short-circuit pickup at 5 to 10 times the rated current In=250 A. N-conductor protection is set at 100%. The nut keeper kit included with this variant (ZD00 suffix) is specified for DC Power OEM applications in China — the kit retains the terminal nuts during transport and vibration, a detail that matters if the breaker ships as part of a pre-wired assembly rather than as a loose component.","metaTitle":"Siemens 3VA1225-5GF42-0AA0-ZD00 Circuit Breaker, 250A, 55kA","metaDescription":"Siemens 3VA1225-5GF42-0AA0-ZD00 IEC frame 250 circuit breaker, 55kA Icu @ 415V, 4-pole, TM240 ATAM, In=250A, Ir=175-250A.
