Anstoss Ignition transformer ZAG 2V 07000066

This Anstoss ZAG 2V ignition transformer (SKU 07000066) operates on 220–240 V at 50–60 Hz and consumes 3 W. It generates a high-voltage pulse for ignition in gas and oil burners used in domestic and industrial boilers. The transformer is rated for ambient temperatures up to 85 °C, measures 80 x 45 x 35 mm, and has a net weight of 0.174 kg. It comes with a silicone-insulated ignition cable and is energized only during the ignition phase.

Ignition transformers of this type are selected by matching the primary voltage to the burner control supply (typically 230 V AC, with 110 V and 24 V variants available), the secondary output to the electrode gap requirements, and the duty cycle (peak or continuous) to the application. Compare mounting dimensions, fixing centres, terminal layout, and the high-tension cable connector pattern with the original unit. The ignition cable must be silicone-insulated to withstand high voltage and heat. Verify that the physical size and fixing centres match for a direct mechanical fit before ordering.

When ignition transformers of this kind fail, the burner may not ignite or may ignite intermittently. A cracked or hardened silicone cable can leak the spark to earth, mimicking a faulty transformer. Inspect the cable for damage and confirm that the control box energizes the transformer only during the ignition phase.
