Three-phase safety isolating transformers with the power between 0,05 and 16 kVA

Description

Three-phase safety isolating transformers are assigned for supplying electric devices with safe voltage.
In standard design, the transformers are adjusted to fastening by means of screwed angles.
The windings terminals may be placed on one side only, or on both sides of a transformer. Upon request, the transformers may be assembled in enclosures with the protection degree of IP 23, IP 44 and IP 54.
