Three-phase current transformers for use with UMC Universal Motor Controllers

The ABB CT4L and CT5L current transformers are accessories for the UMC100 Universal Motor Controller 

At motor currents of more than 63A an additional external current transformer is needed. Just four different variants extend the nominal current range up to 850A.


Main features

• For use with UMC and nominal motor currents >63 A
• Only four variants cover up to 850 A
• Current transformer with linear characteristics

The motor current flows through the current transformer.
The UMC measures the secondary current (4 A at nominal current) and calculates the real current based on the parmater setting ‚Current Factor‘.
More information how to set this parameter is available in the UMC manuals.
