It carries a TM220 thermal-magnetic trip unit — the thermal element adjustable from 175 A to 250 A, the magnetic fixed at 10× In. The 70 kA Icu at 415 V puts this in breaking capacity class H — the highest standard class for the 3VA1 frame. The TM220 trip unit gives you thermal adjustment from 175 A to 250 A (the Ir range), so you can fine-tune overload protection to the actual continuous load without swapping the breaker body. Magnetic pickup at 10× In (2500 A) is fixed — that's a standard motor-start or cable-protection curve, not a selective or generator-protection characteristic. ## Integration Notes This is a 4-pole breaker with 100% N-conductor protection — the neutral pole is switched and protected, not just a solid link. The nut keeper kit (part of the ZD00 suffix) is factory-fitted for DC Power OEM builds in China; it retains the terminal nuts during panel wiring. Mounts in a standard IEC distribution board or enclosure on a mounting plate — no DIN rail adapter for this frame size.","metaTitle":"Siemens 3VA1225-6GE42-0AA0-ZD00 Circuit Breaker, 250A, 70kA","metaDescription":"Siemens 3VA1225-6GE42-0AA0-ZD00 IEC frame 250 circuit breaker, 70kA @ 415V breaking capacity, 4-pole, TM220 thermal-magnetic trip, 250A.
