Ditek D50-4803DFM 480V 3-phase Surge Protective Device

Product Description

The DITEK D50-4803DFM is a surge protective device (SPD) designed for 480-volt, 3-phase delta electrical systems in a 3-wire plus ground configuration. It suppresses transient voltage events that can damage motors, drives, controls, and other sensitive equipment connected to the distribution system. Surge protection devices in this class are typically installed at the service entrance or sub-panel level. Licensed electricians install and commission this type of device in commercial and light industrial applications where 480V 3-phase delta power is present.

This SPD is suited for 480V 3-phase delta systems commonly found in commercial buildings, manufacturing facilities, and industrial process equipment installations. The 3-wire plus ground configuration matches standard delta wiring topology used across a wide range of electrical distribution panels. It provides point-of-use or panel-level transient surge suppression to protect downstream electrical and electronic equipment from voltage spikes caused by lightning, utility switching, and load-switching events.

Key Features

• Rated for 480V AC 3-phase delta electrical systems
• 3-wire plus ground configuration matches standard delta panel wiring
• Designed for transient overvoltage suppression at the panel or service entrance level
• Sold as an individual unit for direct installation by a licensed electrician

Compatibility

Designed as an OEM-style surge protective device for 480V 3-phase delta, 3-wire plus ground electrical distribution systems. No specific panel or equipment compatibility data was provided in the product input.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NFPA 70 (NEC) Article 285 governing surge protective devices. De-energize the panel completely and verify absence of voltage before making any connections. Follow the manufacturer wiring instructions and local AHJ requirements for conductor sizing and overcurrent protection. Do not exceed the rated system voltage for this device.
