It carries the TM220 thermal-magnetic trip unit (ATFM) with adjustable overload protection from 70 A to 100 A and fixed short-circuit protection at 10 × In. The 100% N-conductor protection means the neutral pole is fully rated — no derating needed for unbalanced loads or harmonics, which matters for panel builders feeding mixed single-phase and three-phase gear off the same bus. The adjustable Ir (70–100 A) lets you match the breaker to the actual load current — useful when the design load is below the fixed In. The fixed Ii = 10 × In means magnetic trip kicks in at 1000 A, so it coordinates well downstream of a larger feeder breaker with a higher short-time pickup. ## Deployment Context This is a panel-mount MCCB for IEC distribution boards. The 4-pole format is standard for three-phase plus neutral in TN-S or TN-C-S systems. The nut keeper kit for DC Power OEM suggests it was originally specified into a DC-side application — verify polarity and arc extinction if repurposing for DC, as the magnetic trip and arc chambers are calibrated for AC waveforms by default.","metaTitle":"Siemens 3VA1110-3GE42-0AA0-ZD00 3VA1 IEC Frame 160 100A MCCB","metaDescription":"Siemens 3VA1110-3GE42-0AA0-ZD00 circuit breaker, 3VA1 IEC frame 160, 4-pole, 100A, breaking capacity 25kA @ 415V.
