What it is
The Siemens QRB1B-A050B70A is a photo cell used in oil-fired boiler burner assemblies to monitor the flame. It is listed by Siemens under the oil spares range and is held against the QRB 1B-A050B70A2 catalogue reference. The cell provides the flame signal that the burner control uses to supervise combustion.
Before you order
- Compare the part number on the existing cell with QRB1B-A050B70A before ordering.
- Confirm the burner or boiler model against Siemens documentation for the oil spares range.
- Check the quantity required, as some burner assemblies use more than one cell.
