Dimensions:

Solid-state switches that operate when the AC current level sensed by the internal current transformer exceeds a fixed set point. Internal circuits are totally powered by induction from the conductor being monitored. There is zero off-state leakage current in the solid-state relay output that can switch AC or DC circuits. Currents up to 250A can be monitored. For higher currents or larger diameter conductors, an external current transformer should be used.
