Danfoss Ignition cable 052F5052

The Danfoss 052F5052 is an ignition cable designed for use with the Danfoss EBI4 transformer. It is silicone-insulated to withstand the high voltage delivered by the transformer and the heat near the burner. This cable connects the ignition transformer to the ignition electrode, carrying the high-voltage pulse without leakage. It is categorized under ignition cables and connectors.

When selecting a replacement ignition cable of this type, the critical parameters are the connector pattern at both ends—one to the transformer terminal and the other to the electrode—and the cable length, which must be sufficient to reach without tension or sharp bending. The cable must be rated for the same peak voltage as the transformer; a cable with inadequate insulation will break down internally. Ensure the new cable is routed away from sharp edges and hot surfaces.

A common fault on burners is a spark that jumps to ground instead of crossing the electrode gap, often caused by a hardened or cracked ignition cable rather than a failed transformer. Signs of aging or damage include carbon tracking, brittleness, or physical damage. Before replacing the transformer, always inspect the cable for these issues and replace any cable that shows signs of age or damage.
