Measuring transformers encapsulated in resin

TRM140 3000/5A

TRM140 3000/5A, Measuring transformers encapsulated in resin

Code: P50156.

  • Inner diameter (mm): 140
  • System: Single-phase
  • Class 0,5 Power (VA): 35
  • Measurement Range (A): 3000/5
  • Input current: 3000 A
  • Transformer type: Encapsulated in resin

INFORMATION

Description

Resin-coated current transformer, busbar. Other characteristics:

  • From 75 to 5000 A
  • Inner diameter from 30 to 180 mm, according to type 
  • Secondary .../5 A ( .../1 A on request)

Applications

These transformers have been conceived to convert nominal currents in any installation to current values adjusted to measurement devices. Its synthetic resin increases its resistance to adverse environmental conditions.
