Ditek DTK-120/240CM+ 120/240 V Single-Phase Arrester

Suppress transient overvoltage on 120/240 V single-phase power circuits while providing a visible LED status signal. Ditek DTK-120/240CM+ is specified for this voltage and phase arrangement, giving engineers a clearly matched arrester choice where the protected circuit uses 120/240 V single-phase power. The LED provides a direct local condition indication rather than requiring the device to be identified only by its enclosure label. Select this configuration when circuit voltage and phase count are primary compatibility constraints. A 120/240 V single-phase designation identifies the electrical arrangement the arrester is intended to support, making it more useful than selecting protection hardware by physical fit alone. LED indication supports visual inspection in installations where personnel need a local status cue at the protective device. Use this unit as a power-protection component in electrical infrastructure built around a 120/240 V single-phase supply. Its selection criteria center on three concrete attributes: 120/240 V operation, single-phase application, and LED status indication. Installation location, enclosure type, conductor connections, surge-current rating, and protection-mode requirements should be evaluated against the protected circuit and site electrical design.
