Description

Current transformers of type ASG 123 are one-phase low voltage current transformers. A fully covered resin hardened measuring system, as well as a newly designed mounting assembly for the bus bar, ensure the safe accomodation of transformers during excessive high mechanical demands, i.e. generator oriented plant. The materials used for the production of transformers allow a high degree of climatic continuance and electrical safety. The modular designed housing ensure a space saving integration of up to three differing measuring system in one enclosure.

When ordering please state a defined, flexible length of the secondary connection leads as this will reduce assembly time and eliminate additional wiring.

All cable ends are fitted with wire ends and a clear connection recognition, according to international standards.

Aditional sheathing made of helical woven tissue equivalent material are giving protection against mechanical damage of the isolation of the connection leads.

These current transformers are made to order. We offer you a primary current range of 1000-4000 A, and as standard a secondary current of 5A or 1 A. Further values can be considered and realized for deliveries.

This current transformer is availble in classes 0.2, 05, 0.5s and 1 and in the protection classes 5P10,10P10, 5P20, and 10P20.

The production is according to DIN EN 60044/1 and DIN VDE 0414, issue 1
