Short-circuit pickup (Ii) is fixed at 10 x In, so 500 A instantaneous. That's a standard motor-starting curve; it rides through inrush on a 30–40 A motor but trips fast on a hard phase-to-phase fault. The N-conductor protection is set to 100 %, meaning the neutral pole tracks the phase poles — common for 4-wire systems where the neutral carries harmonic or unbalanced current. The nut keeper kit (part of the D00 variant) retains the terminal nuts during wiring — saves time on a production line or panel shop. Four-pole means it occupies the full width of a 160 A frame; check the enclosure fill factor if you're retrofitting into an existing MCC bucket.","metaTitle":"Siemens 3VA1150-4GE42-0AA0-ZD00 MCCB, 50A, 36kA @ 415V","metaDescription":"Siemens 3VA1150-4GE42-0AA0-ZD00 IEC frame 160 MCCB, 50A TM220, 36kA @ 415V.
