It carries a TM220 thermal-magnetic trip unit with ATFM (Adjustable Thermal Fixed Magnetic) — overload protection Ir adjustable from 112A to 160A, short-circuit protection fixed at Ii=10 x In. This order code is configured for a DC Power OEM in China. The 55kA Icu at 415V places this breaker in breaking capacity class M — suitable for industrial panelboards and distribution systems with moderate fault current levels, such as those fed by a transformer in the 1000-2000 kVA range. The TM220 trip unit with ATFM gives you adjustable thermal protection (Ir 112A-160A) for cable or busbar protection, while the fixed magnetic pickup at 10x In (1600A) clears hard shorts fast. ## Integration Notes This is a 4-pole DIN-rail mountable breaker in the 3VA1 frame — fits standard Siemens panelboard and distribution board footprints. The unprotected N conductor should be wired to a solid neutral bus, not through the breaker poles. Verify that the fixed Ii=10xIn setting coordinates with downstream breakers for selectivity — the high magnetic pickup may require careful grading with branch-circuit MCBs.","metaTitle":"Siemens 3VA1216-5EE42-0AA0-ZD00 Circuit Breaker, 160A, 55kA","metaDescription":"Siemens 3VA1216-5EE42-0AA0-ZD00 IEC frame 250 circuit breaker, 4-pole, 160A, Icu=55kA @ 415V.
