WTB5-BK is a 5 way 100A single pole terminal block in black, designed to accommodate conductors from 2.5 mm² to 35 mm². It provides a compact and secure solution for distributing multiple outgoing conductors in electrical installations where a robust terminal block is required.
Like the wider WTB5 range, this terminal block features a lockable, sealable lid and is supplied with blanking pieces for unused connection points. Its hexagon screw design helps keep conductors firmly secured, making it suitable for residential, commercial, and small industrial applications.
Installer Tip: Use the black variant where your installation or site labelling scheme calls for a distinct identification colour, while keeping unused ways safely sealed with the supplied blanking pieces.
