Porduct Overview

EKDB11S is a compact, IEC 61439-3 compliant single-phase plug-in distribution board designed for fast, safe, and clean low-voltage power distribution in residential and small commercial spaces. Perfect for apartments, retail units, small offices, and especially retrofit projects requiring quick installation with minimal disruption.

Engineered for efficiency, the EKDB11S features a standardized plug-in interface for branch circuit devices, supporting both plug-in MCB and plug-in RCBO options. Available in surface-mounted (EKDB11SS) and flush-mounted (EKDB11SF) versions with consistent internal layouts, this distribution board accommodates main switches up to 125A with options for an Isolation Switch or an RCCB (without overcurrent protection).

The thoughtful design includes ample space for cable routing, multiple easy-access knockouts, and generous neutral/earth terminal capacity. With 4 to 16 outgoing ways available, the EKDB11S provides versatile options for various residential and small commercial applications while maintaining installation simplicity and future maintenance ease.

Fast Installation: Plug-in branch circuit interfaces minimize wiring time, perfect for retrofit projects
Easy Maintenance: Replace breakers or add circuits with limited wiring rework thanks to standardized busbar layout
Flexible Mounting: Choose surface-mounted (EKDB11SS) or flush-mounted (EKDB11SF) versions with identical internal configurations
Compliant & Safe: Fully IEC 61439-3 compliant design with IP40 protection rating
Generous Terminal Capacity: Ample earth and neutral terminals with outgoing terminals ≥ number of ways
Space-Efficient Design: Compact form factor with multiple knockout options for neat cable management
Expandable: Scalable options from 4 to 16 ways to suit varying installation requirements
