Product description

Sifam Tinsley 3 phase block current transformers with 70mm centres are built for high current metering at the top end of commercial and industrial distribution systems. With primary ratings of 800A, 1000A, and 1600A and a standard 5A secondary output, this range is suited to incomer metering, main distribution boards, and large-scale sub-metering applications where busbar and large cross-section cable sizes require a wider aperture. The integrated three-phase block format maintains installation simplicity even at these higher current levels, replacing three individual CTs with a single compact unit.

Tekox Terminal Strips Safety Blocks and Porcelain Blocks

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.
