That 36 kA Icu means it can safely interrupt a fault current up to that level without welding contacts or cascading upstream — critical for selectivity studies in distribution panels where downstream faults must be cleared locally. The thermal-magnetic trip unit (TM240) gives you adjustable overload protection (Ir from 175 A to 250 A) and fixed short-circuit pickup (Ii 5 to 10 times In, so 1250 A to 2500 A). This breaker is sized for line protection in OEM DC power equipment built in China, per the special nut keeper kit variant.","metaTitle":"Siemens 3VA1225-4EF32-0AA0-ZD00 Circuit Breaker, 250A, 36kA","metaDescription":"Siemens 3VA1225-4EF32-0AA0-ZD00 3VA1 IEC frame 250 circuit breaker, 36kA breaking capacity @ 415V, 3-pole, TM240 thermal-magnetic trip, adjustable Ir 175-250A, Ii 5-10xIn.
