Siemens ZE23 8.5 High Voltage Ignition Transformer

Siemens ZE23/8.5 high-voltage ignition transformer is a ballast/ignition transformer used to generate the electrical spark that ignites burners in gas-fired equipment; the unit accepts a standard 230 V AC mains supply and converts it to a high-voltage secondary capable of about 7 kV, delivering up to 30 mA to the ignition electrode when the control circuit triggers the spark sequence. This ZE23/8.5 designation identifies the model within Siemens' ignition transformer family, and retailers and distributors list it as a replacement part for burners that require the ZE23/8.5 specification; it is commonly deployed in installations where a compact, dedicated high-voltage source is needed to initiate flame, without routing ignition energy through the main control circuit. Potential buyers should verify compatibility with their burner controller and ignition module to ensure the 230 V input and 7 kV/30 mA output meet the system's ignition energy requirements, and to confirm the physical form factor and connector arrangements align with the existing installation.
