allowing individual faulted fixture to be assessed
and serviced without affecting the rest of the circuit
• Increases efficiency by preventing faulted ballast
from severely damaging fixture or device
• Watertight seal
• Fiberglass reinforced polymer body resists damage
from impact (better than phenolic look-a-likes)
• Variety of terminations available for flexible design
• Ultrasonically-welded terminals provide maximum
strength and eliminate leakage

for applications where light poles may be accidentally
knocked-down
