Circutor, S.A. - Differential relays
Circutor WRN-22
Differential protection: ideal for spaces reduced
The differential protection WRN-22 of Circutor is a very interesting solution in those installations where does necessary a protection of high range but has of a space reduced.
With the WRN-22, can use any magnetotérmico of the market like element of cut of the differential protection, with so alone associate him a coil of broadcast (if it does not have of her).
The WRN-22 can use so much in installations of two poles as in installations of four poles.
Between his technical characteristics fits to stand out the electronic relay Type To, the measure in TRMS, the transformer incorporated, with step of cables of 22 mm of diameter and the sensitivity of 30 or 300 mA, according to model.
The time of retardo fixed is to 20 ms, integrates detection of presence of tension by means of a led and button of test.
It is adapted for installations until 63 To (2x25 mm2, 4x16 mm2) thanks to his reduced size of 3 modules.
