The ULTECH tin-plated aluminum dual-rated neutral bar is machined from 6061-T6 aluminum alloy and finished with an electro-tin plating layer, creating a common termination point for neutral conductors in power distribution panels, switchgear, and industrial control cabinets. The tin-plated surface blocks galvanic corrosion when mating copper conductors while maintaining full compatibility with aluminum wires, eliminating the need for separate busbar inventories. Available in DCK, LS, and LL series with up to 100 termination positions, the bar features precision-machined chamfered wire entry holes and captive set screws for secure, low-resistance connections across commercial, industrial, and renewable energy installations. UL 486A/B Recognized (File No. E528529).
