Juno® 277 VAC, 2-circuit/2-neutral, HTEK Series HD commercial trac is ideal for dimming intensive applications. The independent neutrals guarantee that the 2 circuits are completely isolated. The potential for cross-circuit interference and neutral harmonics is completely eliminated, ensuring trouble free dimming. The trac's extruded aluminum construction and continuously crimped conductors ensure mechanical strength and electrical reliability. Its integral suspension rail and predrilled mounting holes simplify installation.
