Switch – Fuses (Protects and isolates Capacitor Steps)
Fully shrouded fused isolators are used to isolate and protect either the Power Factor Correction system and/or the individual steps. These are bus bar mounted and contain DIN fuses suitably rated for protection of each capacitor step and connecting cables (125 Amp for 50kVAr and 63 Amp for 25kVAr steps).
Switching ratings:
- Step Switch-Fuse – 160 Amp
- Making Capacity – 40kA
- Impulse Voltage – 8kV
- 400 Amp , 630 Amp, 800, 1250 Amp
- Making capacity – 100kA
- Impulse Voltage – 12kV
- Fuses – DIN – To IEC 269-2-1 Breaking Capacity 120kA (size 00-2)
