Kromschroder Ignition transformer 84391270

Kromschroder ignition transformer 84391270 is a device that steps up the mains voltage to produce a spark for igniting gas or oil in burners. It operates with a supply voltage of 230 V and is insulated on the secondary side. This transformer complies with the machinery directive 2006/42/EC and meets the standard CSA C22.2 No. 13-1962.

When selecting an ignition transformer of this kind, key parameters include primary voltage (230 V is standard, but 110 V and 24 V versions exist for certain control circuits) and secondary voltage and current rating, which must match the electrode gap and burner type. Duty cycle is also relevant: a transformer that overheats on continuous operation will fail prematurely. Mounting style and terminal pattern must align with the existing bracket and cabling. Always inspect the high-voltage cable and boot before replacing the transformer itself.

Typical failures include overheating due to excessive duty cycle, leading to premature failure. A hardened or cracked high-voltage cable can cause the spark to leak to earth, which may be mistaken for a faulty transformer. Check the cable and boot for damage before replacing the transformer.
