The TM220 thermal-magnetic trip unit gives you an adjustable overload band from 88 A to 125 A (Ir) and a fixed short-circuit pickup at 10 x In (Ii = 1250 A). That 10x multiplier is standard for motor-circuit coordination; it rides through normal inrush but clears a bolted fault fast. The ATFM designation confirms the magnetic trip is fixed, not adjustable, so what you see on the nameplate is what you get for instantaneous protection. ## What the 70 kA Icu means for selectivity The 70 kA Icu at 415 V puts this breaker in the high-fault tier of the 3VA1 family — class H. For comparison, the standard class N version of the same frame carries 36 kA at 415 V. The trade-off is a slightly higher let-through energy (I²t) on low-level faults, but for most industrial switchboards the 70 kA rating is the safer call. Frame 160 means the breaker footprint matches the standard 3VA1 cutout — 105 mm wide per pole, so three poles occupy about 315 mm on the DIN rail or mounting plate. The nut keeper kit retains the line-side lug hardware; torque the main connections to the Siemens-recommended value (typically 35–40 Nm for this frame, verify on the nameplate).","metaTitle":"Siemens 3VA1112-6EE32-0AA0-ZD00 Circuit Breaker, 70kA @ 415V","metaDescription":"Siemens 3VA1112-6EE32-0AA0-ZD00 IEC frame 160 MCCB, 3-pole, 70kA Icu @ 415V, TM220 ATFM, In=125A, Ir=88-125A.
