Danfoss Ignition transformer EBI4 1P 052F4240

Danfoss EBI4 1P ignition transformer, SKU 052F4240, is a single-pole ignition transformer designed for burner control systems. It measures 170 mm in length, 90 mm in width, and 55 mm in height, with a net weight of 0.24 kg. This transformer steps up the mains voltage to create a spark for fuel ignition during the ignition period. It is manufactured in Denmark.

When selecting a replacement ignition transformer of this type, verify the primary voltage (commonly 230 V, but 110 V and 24 V variants exist), required secondary voltage and current, duty cycle, and mounting and terminal connections. Check the physical dimensions and terminal layout against the burner's specifications. Ensure the ignition cable is silicone-insulated and in good condition before installation.

Typical failures include internal short circuits or open windings, leading to no spark or weak spark. The burner may fail to ignite or lock out. Check the ignition cable for hardening or cracks, as these can cause spark leakage to earth, misdiagnosed as transformer failure.
