INFORMATION

Description

The range of TQR transformers has been designed to facilitate the installation through its split core that allows for its placement without interrupting the supply, both in installations with cable and with flat beds. Its main features are:

  • Types up to 2000 A of current
  • Codifiable types in secondary current ... /5 A, .../1 A and ... /250 mA
  • 80 mm rounded inner diameter
  • Certified transformers
  • Possibility of clamping bedplate with flange

Applications

Ideal for installations where it is not possible to interrupt the power supply to install the transformers.
