Series TTM
Three-phase - single-phase transformer
Series TTM
Three-phase - single-phase transformer
Isolation transformer converting three-phase voltage 400 V into single-phase voltage 230 V.
Protection rating according to installation requirements:
- IP00 without enclosure
- IP23 enclosure for indoor use
- IP65 enclosure for outdoor use.
Features
- Minimises the unbalance in the three-phase mains supply caused by high-power single-phase loads.
- Allows single-phase loads to be fed into three-phase loads without neutral.
- Robust and complete varnishing protects against moisture, dust and corrosion.
- IP20 terminal connection protects against direct voltage contact, up to 20kVA in IP00/23 and 16kVA in IP54.
- Optional cURus marking according to UL up to 100kVA for IP00.
