Brahma Ignition electrode K3A1 12434202

This ignition electrode (model K3A1, SKU 12434202) is for Brahma BR81 burners. It uses ionization flame detection and is made with a ceramic insulator and a heat-resistant contact. It mounts in the burner head, in the flame zone. The design was developed specifically for Eurosystem.

Parts of this type are selected by matching the physical layout: electrode length, bend angle, insulator diameter, the gap between electrode tip and ground, and the type of mounting flange. The manufacturer shapes each electrode for a specific burner series, so the geometry must match the combustion head and intended spark gap. When replacing an electrode, verify that the new part matches the original in overall shape, insulator dimensions, and mounting pattern. The burner control and ignition transformer must also be compatible; the electrode itself does not carry a voltage rating—only electrical clearance and creepage distance matter.

Common failure modes include erosion of the tip, cracking of the ceramic insulator due to thermal shock or overtightening, sooting from incomplete combustion, and a drifting gap that gradually extends the ignition time. The equipment may show delayed ignition or fail to light when the gap grows or the insulator cracks. During inspection, check for these conditions and compare the electrode with the original to confirm correct geometry.
