INFORMATION

Description

The TDH series transformers are high precision current transformers with an improved design that meet all the needs of today's installations. They are versatile devices when it comes to mounting and fixing, and they are sealable, with the aim of avoiding any manipulation.

Main features:

  • Type: bar entrance
  • From 60 to 4000 A
  • Test Report
  • DIN rail fixing accessory
  • Sealable
  • Secondary .../5 A, .../1 A and .../250 mA (consult availability)
  • Diameters from 20 to 63 mm

Applications

These transformers have been conceived to convert nominal currents in any installation to current values adjusted to measurement devices.
