TRTM2,5

Three-phase to single-phase 2.5kVAtransformer with IP23 metal enclosure, allows the adaptation of three-phase to single-phase lines and 400Vac to 230Vac voltages. It provides galvanic isolation.

This type of transformers are not reversible, i.e. they cannot transform a single-phase line to three-phase.

The transformer is supplied without any type of overload protection, it is mandatory to install them to avoid overloading the transformer. The power and current indicated are apparent, the active current provided by the transformer will depend on the power factor of the connected load.
Material for professional use, install in compliance with the regulations in force at the place of installation.

Questions

Question
Bonjour , pouvez vous me dire la protection qu'il faudra mettre en entrée du transformateur . Cordialement Mr EGLOFF
Answer
Bonjour,

Pour la protection à l’entrée du transformateur doit mettre un magnéto-thermique qui dépendra de la section du câble. Si le câble est de 1.5mm2 une courbe magnétothermique C de 10A, si le câble est de 2.5mm2 une courbe magnétothermique C de 16A. À la sortie du transformateur doit également le protéger avec un magnétothermique courbe C de 2A .
