Individual fixture fusing-Prevents loss of one fixture through accident, vandalism, or end of life from darkening the entire circuit. Simplifies maintenance- Being able to immediately identify the one faulted fixture eliminates testing the entire circuit, speeds repair and permits servicing the individual unit while the rest of the circuit is functioning. Reduces damage from fault-Can prevent faulted ballast or other failure from severely damaging fixture or device, reducing necessary repair or need of replacement. Features: Watertight-Internal O-ring provides watertight seal. Superior terminal seeds-Ultrasonically-welded terminals provide maximum strength and eliminate leaking at terminals. Break-Resistant- Fiberglass –reinforced polymer body resists damage from dropping or impact much better than phenolic look-alikes. Flexible terminations-Accommodates a wide range of stranded or solid copper conductors, with either crimp or screw terminals. One-pole and two-pole models- available to accommodate all system voltages up to 600v.
