Drawing

Quick Selection Check

1. Rated voltage → Select 7.2kV / 12kV / 24kV / 40.5kV

2. Rated primary current → According to load or busbar specifications (100A, 300A, 600A, 1,250A)

3. Accuracy and load → Measurement 0.2S/0.5 (10-20 VA); Protect 5P10/10P15 (15-30 VA)

4. Short-time thermal current → Match the system short-circuit current (20 kA, 31.5 kA, 50 kA, 80 kA/1 s)

5. Installation method → Pillar upright/side installation/upside down installation; The base is fixed with 4-M12 expansion bolts

6. Special Requirements: High altitude 3,000m, low temperature -40 ℃, anti-pollution Grade III, dual transformation ratio, tap type, with shielding cover
