Series TT
Three-phase isolation transformer
Series TT
Three-phase isolation transformer
- Three-phase transformer with galvanic isolation between primary and secondary.
- Protection rating according to installation requirements:
- IP00 without enclosure
- IP23 enclosure for indoor use
- IP65 enclosure for outdoor use.
Features
- Eliminates the risk of accident in the event of single-pole contact.
- Allows the supply of single-phase loads in networks without neutral, maximum unbalance between phases of 30%.
- Robust and complete varnishing protects against humidity, dust and corrosion.
- IP20 terminal connection protects against direct voltage contact, up to 31kVA in IP00/23 and 25kVA in IP54.
- Optional cURus marking according to UL up to 100kVA for IP00.
