Dual Voltage Load Box, 120/208V 277/480V
- Helps prevent damaging effects of ferroresonance found on lightly loaded or unloaded 3-phase power systems during single phase switching
- Ferroresonance typically occurs on medium voltage distribution transformers and power cables during single phase switching
- Overvoltage leads to insulation breakdown resulting in damage to the transformer, lightning arresters andother equipment
- 5,000 watt per phase loading
- Resistive load up to 3 phases
