Ditek D50-120/2083Y 50ka 120/208V 3-phase Surge Protector

Product Description

The DITEK D50-120/2083Y is a surge protective device (SPD) rated at 50 kiloamperes (kA) per mode, designed for 120/208-volt three-phase wye electrical systems. It carries a UL 1449 3rd Edition listing, the current standard for SPDs in the United States. This unit clamps transient overvoltages caused by lightning, utility switching, and internal load switching before they reach downstream equipment. Licensed electricians install this device at the service entrance, distribution panel, or sub-panel level to protect sensitive loads in commercial, industrial, and institutional facilities.

The D50-120/2083Y is suited for three-phase wye distribution systems operating at 120/208 volts, which are common in commercial office buildings, retail spaces, light industrial facilities, and multi-tenant structures. The 50 kA surge current rating makes it appropriate for installations where high-energy transient exposure is a concern, such as buildings with significant mechanical or motor loads, or those located in high-lightning-incidence areas. It ships as a single unit intended for permanent panel-mounted installation.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes governing surge protective devices. De-energize and lock out the panel before making any connections. Follow the manufacturer wiring diagram for proper phase, neutral, and ground terminations. Verify system voltage and configuration match the device rating before energizing.
