Switch Fuses
Available options include three- and four-pole configurations for NH/DIN and BS fuse systems. The range covers multiple current ratings from 63A to 400A, with models supplied or configured with the appropriate handle and operating shaft.
Enclosed switch fuses are available in sheet-steel and polycarbonate enclosures. Open-type models provide a compact solution for integration into control panels, switchboards and power-distribution equipment.
When selecting a switch fuse, consider the fuse system, operational current, utilisation category, number of poles, mounting arrangement, enclosure material and required handle or shaft. Always confirm the complete manufacturer specification against the installation requirements.

Tekox Terminal Strips Safety Blocks and Porcelain Blocks

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.

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.
