Kromschroeder 75454621 FE300 electrode

The Kromschroeder 75454621 FE300 electrode belongs to the category of ionization and ignition electrodes used in gas burners. Parts of this type perform one of two roles: an ignition electrode delivers a spark from the ignition transformer to light the fuel-air mixture, while an ionisation electrode proves the presence of flame by conducting a small rectified current through it. Both types are positioned directly in the flame zone and are considered consumable items. Over time, the tip may erode, the ceramic insulator can develop cracks, or soot deposits can accumulate, and the spark gap may drift – all of which can lengthen ignition time or cause lockout. When selecting a replacement electrode, the key parameters are the overall length, the bend angle of the rod, the diameter of the ceramic insulator, the spark gap (distance between electrode tip and burner earth), and the shape of the mounting flange or bracket. These dimensions must match the burner head geometry and the electrode holder on the burner plate. In many burner designs, a pilot burner carries a small permanent or intermittent flame that lights the main burner and holds the flame signal via a separate ionisation electrode. The Kromschroder electrode listed here is specified by the manufacturer code 75454621 and catalogue article 624.946.024; always verify that the physical dimensions and mounting arrangement match the existing electrode before installation. No further technical details are available for this specific article beyond its name and codes.
