The DITEK DTK-120/240HD2 is a heavy duty surge suppressor designed to protect sensitive electrical equipment from transient voltage events, including lightning strikes and power line disturbances. Built for demanding commercial and industrial applications, this device clamps excess voltage before it can reach downstream equipment. Licensed electricians and electrical contractors typically specify and install this unit in service entrance or distribution panel applications where robust surge protection is required.
The DTK-120/240HD2 is suited for 120/240-volt single-phase electrical systems commonly found in commercial buildings, light industrial facilities, and large residential service entrances. It provides whole-system protection at the point of entry, helping to safeguard HVAC controls, building automation systems, and other critical electrical loads connected downstream.
Designed as an OEM-style replacement or direct-install surge suppressor for 120/240-volt single-phase electrical distribution and service entrance panels in commercial and light industrial applications.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the panel and verify the absence of voltage with an appropriate meter before making any connections. Follow the manufacturer data sheet for proper wiring configuration and bonding requirements. Do not install with power live.
