Modular busbar systems that streamline power distribution, improve safety, and speed up panel builds.
Great electrical installations don't fail because of the major components. They fail because of the small ones that didn't get enough attention.
It's easy to focus on the big-ticket items during specification — and let the terminal blocks become an afterthought. But inferior connection components have a habit of making themselves known over time. Loose connections, degraded insulation, premature failure. The kind of faults that are frustrating to trace and expensive to fix.
Tekox engineer their terminal strips, safety blocks, insulated strips, and porcelain blocks to the standards your installations deserve. Available now from Demesne Electrical — get in touch and we'll show you the range.
Conta-Clip PPVK push-in potential distribution terminals simplify control cabinet wiring with tool-free connections, compact DIN rail mounting, and reliable current distribution up to 41A.
The PMX fuse holder range is compact, halogen-free, and manufactured in Europe for fast availability. Available in 10×38, 14×51, and 22×58 sizes with IEC, UL, and CSA approvals, they feature silver-plated contacts, IP20 touch-safe design, and optional blown fuse indicators — giving panel builders reliable, safe, and flexible protection.
We’re excited to share some great news at Demesne Electrical. Wayne Moody has joined our team, bringing with him years of experience and a clear vision for the future. His focus will be on building on our strong reputation here in Ireland and driving our growth across Europe.
