For a 100A feeder, 55kA SCCR at 415V provides generous headroom for most industrial distribution panels, meaning selectivity coordination with downstream breakers is easier to achieve. The ATFM designation indicates a fixed thermal-magnetic trip with adjustable thermal (Ir) and fixed magnetic (Ii). The N-conductor protection is set to 100%, so the neutral pole is fully rated — important for systems where neutral current can approach phase current, such as in nonlinear loads or 4-wire distribution. The nut keeper kit and DC Power OEM in China note suggest this variant is configured for a specific OEM assembly — the nut keeper secures the breaker in a panel or enclosure where vibration or repeated access could loosen standard mounting. If you are replacing an existing unit in a DC Power OEM cabinet, this is the exact fit.","metaTitle":"Siemens 3VA1110-5GE42-0AA0-ZD00 Circuit Breaker, 100A, 55kA","metaDescription":"Siemens 3VA1110-5GE42-0AA0-ZD00 IEC frame 160 circuit breaker, 100A, Icu=55kA @ 415V, 4-pole, TM220 overload, ATFM.
