TUP_R / TUP50PR / TUP80R cast large-window current transformers, 100–6000 A, for measurement and protection
Country: Spain · Model: TUP_R / TUP50PR / TUP80R
The cast feed-through TUP_R, TUP50PR and TUP80R current transformers have a large window and work with primary currents from 100 to 6000 A. One of the models combines a measuring and a protection winding in one housing. They are installed at the incomers and sections of main switchboards, in busways, on the 0.4 kV side of substations and in generator panels.

Description
The housing is filled with resin, which gives good insulation and mechanical strength. The measuring TUP20RC, TUP20R, TUP60R and TUP95R are designed primarily for 80×20, 100×20, 100×60 and 100×95 mm busbars, but also fit Ø20, Ø20, Ø60 and Ø95 mm cable. Currents are 500–5000 A, classes 0.5 and 1, burden 10–25 VA. TUP50PR has two secondary windings, for example class 1 at 15 VA for measurement and 5P20 at 5 VA for protection, a Ø50 mm window and currents of 1000–6000 A; the secondary circuit configurations are x/1 A – x/1 A, x/1 A – x/5 A and x/5 A – x/5 A. Classes 0.5, 3 and 5P20 are also available, 0.2S and 0.5S versions on request, and a TUP50PR-D variant. TUP80R has a Ø83 mm window, ratings of 200/1, 500/1 and 1000/1 A, classes 0.2S, 0.5S and 5P10, insulation class A and an operating temperature of −25…+75 °C. The protection TUP_R with a lead cable, for 100–600 A, are convenient for remote relay connection.
How to choose
If the busbar is wide and the current is from 500 A, look at the measuring TUP_R. For combining metering and relay protection in one window you need TUP50PR, where you can choose x/1 A or x/5 A secondaries. TUP80R suits currents of 200–1000 A with classes 0.2S and 0.5S. For smaller windows and a plastic housing, TU_ and TUC_ are better, and for a cast slim profile for 25–6000 A, TU_R.

FAQ
How does TUP50PR differ from the measuring TUP_R?
TUP50PR has two secondary windings, so measurement and protection work from one transformer. For example, class 1 at 15 VA and 5P20 at 5 VA.
What temperature range and insulation class does TUP80R have?
Operating temperature −25…+75 °C, insulation class A. The window is Ø83 mm, with ratings of 200/1, 500/1 and 1000/1 A.
What are the general insulation and overload parameters?
Operating voltage up to 720 V, test voltage 3 kV AC for 1 min, frequency 50–60 Hz, Fs < 5, overload 1.2 In, thermal withstand 60 In, dynamic current 2.5 Ith. Insulation class E, class B (130 °C) on request.
Which standards does the series comply with?
IEC 60185, IEC 61010, IEC 61869-1/-2, UNE-EN 61000-6-1 and 61000-6-3, UL94-V0, VDE 0414, DIN 57414 and BS 3938. A CE declaration is available for the protection TUP_R.
