Ditek DTK-2403CMXPLUS 240V 3-phase Surge Arrester

Product Description

The DITEK DTK-2403CMXPLUS is a 240-volt, three-phase surge arrester with integrated diagnostics designed to protect electrical systems from transient voltage events. Surge arresters in this class intercept damaging voltage spikes on AC power lines before they reach connected equipment. The built-in diagnostic indicator gives technicians a visible status check without removing the device, allowing faster service verification during routine inspections or after a surge event. This unit is sized for commercial and light industrial power distribution applications where three-phase 240-volt service is present.

This surge arrester is intended for installation at or near the main service entrance, sub-panels, or distribution points in commercial buildings, industrial facilities, and other three-phase 240-volt electrical systems. It is typically installed by a licensed electrician as part of a layered surge protection strategy. The diagnostic feature makes it well-suited for locations where ongoing monitoring of protection status is required without panel shutdown.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC Article 285 governing surge-protective devices. De-energize the panel completely and verify absence of voltage with a meter before making any connections. Follow the manufacturer data sheet for proper lead routing and grounding requirements. Do not install on systems with voltage ratings exceeding the device specification.
