If you are looking for a replacement for a relay that is no longer available,
then the following table might help you. The relays that we have suggested are
the nearest replacement currently available. This does not mean that they are the
most suitable, a more modern multi-function relay might be more suitable. Please
contact us for more information, or to request a CD-ROM with all our brochures
on it.
