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
