The overload protection is adjustable via Ir from 175 A to 250 A, and the instantaneous short-circuit pickup Ii is set at 5 to 10 times In (1250–2500 A). This gives the panel builder or site engineer flexibility to coordinate with downstream devices while keeping the main feeder protected. The nut keeper kit noted in the description is a mechanical detail for the DC Power OEM variant destined for China — it retains the terminal nuts during assembly, which is helpful in high-vibration or high-throughput production environments. The 3-pole, 250 A frame size fits typical main feeder or large branch positions in industrial distribution boards, motor control centers, or OEM power distribution units. The thermal-magnetic trip (TM240) is a fixed-trip curve, not electronic, so it is a simpler, more rugged choice for applications where adjustable long-time and short-time curves are not required.","metaTitle":"Siemens 3VA1225-5EF32-0AA0-ZD00 Circuit Breaker, 250A, 55kA","metaDescription":"Siemens 3VA1225-5EF32-0AA0-ZD00 IEC frame 250 circuit breaker, 3-pole, 55kA breaking capacity @ 415V, TM240 trip unit, 250A rated.
