Product Description

The DITEK D100-277/4803Y is a surge protection device designed for 3-phase electrical systems operating at 277/480 volts. It guards connected equipment against transient voltage spikes and surges that can damage motors, drives, controls, and other sensitive electrical loads. This unit is sold individually and is suited for installation in commercial and industrial distribution panels where 3-phase power is present. Licensed electricians and electrical contractors are the primary installers of this class of surge protection device.

The D100-277/4803Y is applicable in commercial and industrial facilities running 3-phase, 277/480-volt distribution systems. Typical installations include manufacturing environments, large commercial HVAC systems, pump stations, and other settings where 3-phase power feeds critical equipment. Surge protection at the panel level helps reduce downtime and protect investments in variable frequency drives, motor starters, and programmable controls.
