Ditek D200-277/4803Y Surge Protector 277/480V 3-phase

Product Description

The DITEK D200-277/4803Y is a surge protection device designed for three-phase, four-wire electrical systems operating at 277/480 volts. It guards connected equipment against transient voltage surges and spikes that can damage or destroy sensitive electrical and electronic loads. This unit is built for commercial and industrial applications where three-phase power distribution is standard. Licensed electricians install this device at the service entrance or distribution panel level to provide whole-system surge suppression on wye-configured 277/480-volt services.

This surge protector is suited for commercial buildings, industrial facilities, and other installations running three-phase 277/480-volt wye power distribution. It is appropriate for protecting motor controls, lighting systems, HVAC equipment, and other connected loads on a four-wire three-phase service. The unit is sold individually and is intended for permanent hardwired installation by a qualified electrical contractor.
