Ditek D200-4803D Surge Protective Device 480V 3-phase

Product Description

The DITEK D200-4803D is a surge protective device (SPD) designed for 480-volt AC, three-phase, three-wire electrical systems with ground. It provides transient voltage surge suppression at the service entrance or distribution panel level, protecting downstream equipment from damaging voltage spikes caused by lightning, utility switching events, and load-generated transients. Licensed electricians install this device as part of a facility's power quality strategy. It is suited for industrial, commercial, and heavy-duty commercial applications where 480V three-phase power distribution is standard.

The D200-4803D is applied in three-phase wye or delta 480V AC distribution systems requiring surge protection at the panel or equipment level. Typical installations include manufacturing facilities, commercial buildings, pump stations, and HVAC equipment rooms where sensitive controls and variable frequency drives are fed from 480V three-phase feeders. The SPD is installed in parallel with the protected load, making it a permanent, always-on protective component of the electrical distribution system.

Key Features

• Parallel-connected surge suppression for continuous system protection
• Designed for service entrance, distribution panel, and equipment-level applications
• Suppresses transient voltage events from lightning strikes and utility switching
• Single unit per installation — sold individually (quantity per package: 1)

Compatibility

Designed as an OEM-style surge protective device for 480V AC three-phase three-wire plus ground electrical distribution systems. No specific compatible panel or equipment model numbers were provided in the product data.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) Article 285 governing surge protective devices. De-energize and lockout the affected panel or distribution equipment before making any connections. The D200-4803D is connected in parallel with the load — verify correct phase, neutral, and ground terminations before re-energizing. Consult the manufacturer datasheet for conductor sizing and lead-length recommendations, as excessive lead length reduces SPD effectiveness.
