Porduct Overview

EKDB11T is a robust, IEC 61439-3 compliant three-phase plug-in distribution board engineered for demanding commercial and light industrial applications. Designed for reliability and installation efficiency, it features fully shrouded busbars and multiple main switch options to accommodate varying load requirements.

Available in both surface-mounted (EKDB11TS) and flush-mounted (EKDB11TF) configurations, the EKDB11T supports three main switch options: 125A Isolator Switch, 125A MCCB, or 250A MCCB. The innovative design includes exclusive height adjustment mechanisms for flush-mounted versions, ensuring perfect alignment between breakers and the dead-front cover.

With branch circuit capacity ranging from 12 to 48 ways, the EKDB11T accepts both plug-in MCB and plug-in RCBO devices, offering exceptional flexibility for various commercial and industrial applications. The distribution board features removable/breakable gland plates, multiple knockout options, and generous wiring space to facilitate neat cable management and streamlined installation.
