The 4-pole construction with 100% N-conductor protection (full-rated neutral) makes it suited for four-wire systems where the neutral carries load current, common in commercial and light-industrial distribution. ## Deployment context The nut keeper kit included (for DC Power OEM in China) simplifies bus-bar installation in DC applications, though the breaker itself is rated for AC distribution.","metaTitle":"Siemens 3VA1112-5GD42-0AA0-ZD00 Circuit Breaker, 125A, 55kA","metaDescription":"Siemens 3VA1112-5GD42-0AA0-ZD00 IEC frame 160 MCCB, 4-pole, 125A, 55kA Icu @ 415V.
