Low voltage - Bushing type current transformer, multict CTM7
Mini current transformers of the multict CTM7 series are inductive, according to the transformer principle of working, single-ended current transformers. They are used to adapt the primary measured value to the input nominal values of the connected measuring instruments.
Based on the applied measuring principle, these current transformers are suitable for use in AC networks only.
The multict CTM7 current transformer series is maintenance-free and designed for primary rated currents of 32 A to 64 A with a secondary rated current of 1 A, in accuracy class 1.
Overview:
multict CTM7 | Round conductor: 7,6 mm Width: 27,5 mm |
Current range: 32 … 64 A |
Highlights
- Due to the small current range also suitable for use in data centers
- Installation directly on 3-phase circuit breakers possible (Phase center distanced: 17,5 mm)
- Quick and easy installation; L1 and L3 transformers are snapped onto the top-hat rail by means of an optional snap-on attachment, L2 transformer is connected to the other two transformer
- Secondary rated current of 1 A, in accuracy class 1
