Anstoss ZAG 2 Var.50Hz 07000050 ignition transformer

This ignition transformer, brand Anstoss, is listed under catalogue article 155.820.035 and manufacturer code 07000050. It belongs to the category of ignition transformers. Parts of this type step mains voltage up to a level sufficient to create a spark across the gap of an ignition electrode. They are energised only during the ignition period of the burner sequence, under the command of the burner control. When replacing such a transformer, the primary voltage is a key parameter – while 230 V is common, 110 V and 24 V versions also exist. Secondary voltage and current ratings must match the requirements of the ignition electrode and the burner design. Additionally, the duty cycle (intermittent operation) and the physical mounting and terminal configuration must be compatible with the existing installation. The ignition cables used with such transformers are typically silicone-insulated to withstand high voltage and heat. A hardened or cracked cable can allow the spark to leak to ground, which may appear as a faulty transformer. Therefore, when troubleshooting a no-spark condition, the cable condition should be checked before replacing the transformer. The transformer itself works in conjunction with the burner control and the ignition electrode, forming part of the safety sequence that ensures proper flame ignition.
