What's New

Install SEL low-voltage reset ground fault detectors on three-phase cables. Its split sensing core allows for installation on cables with diameters of up to 100 mm. The low-voltage secondary source must derive its power from the primary source. Because the primary is disconnected, the GFD will not prematurely reset before primary system restoration. The GFD trips when the vector sum of the currents within the sensing core exceeds the nominal trip rating for longer than 1 ms. The red target remains until the secondary voltage source is restored.

• Submersible vinyl-coated sensing core
• Stainless steel hardware and UV-stabilized materials for excellent weatherability
• Remote display eliminates the need to open the primary
• Highly visible 8 cmI reflective red target display is easy to see
• Display window mounting kit available
• Standard lead lengths -- display to sensor: 2 meters; display to source: 2 meters
