You haven’t found the right split-core current transformer?
You are looking for a split-core current transformer…
…with a better accuracy class, f.e. class 0.2 ?
…as a protection CT, f.e. in protection class 5P20 ?
…with several measuring systems in only one device ?
…or a split-core CT with a bigger opening for your primary conductor ?
Then our fully resin-hardened split-core current transformer type CTO is
exactly the right decision!
Features / benefits
- Split-core current transformer suitable for measuring or protection purposes,
depending on the design of the CT
- The modular design of this series allows a large number of varieties within the
different CT sizes (f.e. two cores in one unit); please see next page for details
about the different dimensions
- Max. operating voltage: 0.72/3/- kV or 1.2/6/- kV; if the primary conductor is
suitably insulated the CT can also be used above 0.72 kV or 1.2 kV
- Primary current range: 50 A … 5000 A
- Secondary currents: 1 A, 2 A or 5 A
- Rated burden: 2.5 VA … 30 VA
- Accuracy classes: 0.2S; 0.2; 0.5S; 0.5; 1; 3
- Over-current rated limiting factor for measuring cores: FS5 or FS10
- Protection classes: 5P / 10P / PX
- Over-current rated limiting factor for protection cores: 5, 10, 15, 20, 30
Dimensions
Inner diameter:
max. 360 mm
Transformer width: 150 – 500 mm
Transformer depth: 60 – 300 mm
Please see next page for details
about the different dimensions.
General technical specifications
- Operating temperature: -5°C < T < +40°C
- Storage temperature:
-25°C < T < +70°C
- Therm. nominal continuous current Icth: 1.0 x IN or 1.2 x IN, other values upon request
- Therm. nominal short-time current Ith: Min. 100 x IN, 1 sec., other values upon request
- Isolation test voltage:
3 kV, Ueff, 50 Hz, 1 min. or
6 kV, Ueff, 50 Hz, 1 min.
- Rated frequency: 50 Hz or 60 Hz, other values upon request
- Isolation class:
E
- Applicable technical standard: DIN EN 61869, part 1 + 2
Further information
- Measuring systems fully hardened with Polyurethane resin
- The current transformers type CTO are intended for subsequent installation in existing low-voltage switchgear. In addition, there are
customers who use these current transformers in medium-voltage switchgears, if the primary conductor is suitably insulated.
- The two parts of the current transformer are held together by four screws with springs or spring clips on the sides, which ensures a
permanent contact pressure.
- The secondary connection terminals are factory-fitted with M5 screws. A clear plastic cover serves as an touch protection.
- Protection type: Housing: IP54, Terminal cover: IP20
- Mounting of CT by means of a baseboard attached to the resin body
- Packaging unit: 1 Stk.
- Customs tariff number: 85043129
