Weight of the device current transformer TOL-10-M-2 - 28kg;
The transformers are manufactured in climatic design "T" and "NF" and are intended for indoor use in:
Height above the sea level - no more than 1000 m.
- Ambient temperature with the heat the air inside the switchgear - from -45 ° C to +50 ° C for the performance of "U2" and from -10 ° C to +55 ° C for the performance of "T2";
- Environment explosive, without dust, reactive gases and vapors in concentrations destroy metal and insulation;
- Working position - any;
In current transformers may be used to account for the secondary windings, Class 0,2 S and 0,5 S with the value of the secondary load below 25% of nominal;
The minimum weight for the device current transformer windings TOL-10-M-2 accuracy classes 0,2 S and 0,5 S is 1B · A;
The certificate on the current transformers with secondary windings for accounting accuracy classes 0,2 S and 0,5 S indicates the measured current and the angular error at rated secondary burden 1B · A;
Can manufacture transformers with different transformation ratios of secondary windings;
The manufacturer guarantees that the quality of the instrument current transformer TOL-10-M-2 technical requirements specifications provided the customer terms and conditions of storage, transportation, installation, operation, and its specified operational documentation.
