Applications & Use Cases

At 200 A rated current and 36 kA breaking capacity, the 3VM1220-4ED32-0AA0 is dimensioned for feeder, sub-distribution and motor-circuit protection in low-voltage main and sub-distribution boards. The TM210 LI trip unit provides fixed overload and short-circuit protection matched to the rated current.

The IEC Frame enclosure supports fixed mounting in form-separated switchgear (form 2–4) and accepts a range of Siemens 3VA accessories — auxiliary and alarm switches, shunt and undervoltage releases, rotary and motor operators — for adaptation to the specific installation and control scheme.
