Overload protection is adjustable from Ir=175A to 250A, and short-circuit protection is set at Ii=5 to 10 times In, giving the commissioning engineer flexibility to match the breaker's trip curve to the downstream load. ## Deployment context This MCCB is designed for panel mounting in industrial switchgear, with a 4-pole configuration that suits three-phase plus neutral applications where the neutral conductor is unprotected (N conductor unprotected). The DC Power OEM in China designation indicates this variant was configured for a specific OEM build — verify the termination and accessory fit against your enclosure layout before specifying.","metaTitle":"Siemens 3VA1225-5EF42-0AA0-ZD00 Circuit Breaker, 250A, 55kA","metaDescription":"Siemens 3VA1225-5EF42-0AA0-ZD00 IEC frame 250 MCCB, 4-pole, 55kA Icu @ 415V, TM240 thermal-magnetic trip, Ir=175-250A.
