It uses a TM240 thermal-magnetic trip unit providing overload protection adjustable from Ir=175A up to 250A and short-circuit protection set at Ii=5 to 10 times In. The 4-pole footprint and frame 250 size require adequate side clearance for heat dissipation and cable bending radius — typical for IEC switchgear layouts. The nut keeper kit is specific to the DC Power OEM build and should be verified against the panel's busbar arrangement before installation.","metaTitle":"Siemens 3VA1225-4EF42-0AA0-ZD00 Circuit Breaker, 250A, 36kA","metaDescription":"Siemens 3VA1225-4EF42-0AA0-ZD00 IEC frame 250 circuit breaker, 4-pole, 36kA breaking capacity at 415V.
