Railway MCB for traction and wayside panels
What the ratings mean for your BOM
Sourcing and lifecycle
The lifecycle stage is marked as current, meaning Siemens continues to manufacture this railway-specific MCB. For a maintenance-spares purchaser, this part is a critical spare to hold in the cabinet before the failure — no spare, no sleep on a legacy railway install. The part is sourced to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time. No official second-source alternate is listed, so dual-sourcing relies on stocking the Siemens part.
