Transformadores de protección TU_CP - Image 2

Protective transformers TU_CP

Manufactured with primary winding, the TU40CP and TU3BCP models allow high currents to be adapted to standard values (x/5A or x/1A), ensuring the correct operation of the protection devices against overloads and short circuits.

The TU40CP protection transformer has a screwed connection terminal. The TU3BCP unit incorporates a horizontal bar in its structure. Both are designed for direct connection by cable or plate.
