0.5 kV
Indoor current transformers
For a rated operating voltage of 0.5 kV, for measuring alternating currents up to 3000 A, for installation in indoor low-voltage switchgear and boards.
Operating conditions
- Ambient temperature−35 to +40 °C
- Altitudeup to 1000 m
- Climatenormal and tropical climate versions
Construction
The transformers are dry-type, cast in epoxy resin. They have their own primary winding made of copper profile conductors or of a bar, depending on the primary current. They are made in normal and tropical versions and meet the requirements of BDS EN 60044-1.
