Series TTH
Three-phase high power transformer
Series TTH
Three-phase high power transformer
Three-phase transformer with galvanic isolation between primary and secondary of high power.
Cylindrical windings and 45º staggered cores.
Protection rating according to installation requirements:
IP00 without enclosure
IP23 enclosure for indoor installation
Features
- Eliminates the risk of accident in case of unipolar contact.
- Foil windings to minimise load losses.
- Anti-flash treatment to protect against humidity, dust and corrosion.
- Magnetic core 45º Step-lap technology to reduce no-load losses and magnetising current.
- Optionally for IP00 possibility of cURus marking according to UL insulation system.
