Key Commercial Data

Country of origin Greece

Technical data

For transformers on ships, saltwater-proof DIN rails must be used

according to the regulations of Germanic Lloyd. This requirement is fulfilled

by all rail designs.

When selecting the type of connection on safety transformers in acc. with

IEC 742/EN 60742/DIN VDE 0551-1, please observe:

- When safety transformers are used as self-contained devices, only

screw connections are permitted for the external connections.
