Contact pieces and arc chutes

Siemens Contact pieces and arc chutes

Wearing parts in the main circuit – replaceable instead of replacing the contactor.

For the large sizes, contact pieces and arc chutes are available as a set. After many operating cycles the contacts erode; replacing these parts restores the original condition and is considerably cheaper than a new contactor. Contact pieces are always replaced as a complete set, never individually.

Parent category: Siemens SIRIUS 3RT contactors.

Product benefits

  • Genuine Siemens parts – fit and ratings match the contactor
  • Wearing parts and spares keep existing plants running instead of replacing them
  • Plug-on and add-on parts need no special tool
  • Clear assignment by series and size – the datasheet values are shown with every article
  • Still available for the older 3RT1 and 3RH1 series as well
