The continuous current rating In = 250 A, with adjustable overload protection Ir from 175 A to 250 A, and short-circuit pickup Ii adjustable from 5 to 10 times In (1250–2500 A). The 4-pole configuration (3 phases + unprotected neutral) suits it for three-phase line entry with a solid neutral bus, common in IEC distribution boards. The nut keeper kit is specific to DC Power OEM builds in China — if you are integrating into a standard AC distribution panel, the kit is included but not required for mounting.","metaTitle":"Siemens 3VA1225-6EF42-0AA0-ZD00 Circuit Breaker, 250A, 70kA","metaDescription":"Siemens 3VA1225-6EF42-0AA0-ZD00 IEC frame 250 circuit breaker, 4-pole, 70kA breaking capacity @ 415V, TM240 overload protection.
