Complete your consumer unit installation with Terelec accessories, compatible with the full DGMET-R consumer unit range. Our accessories range includes DIN rail blank filler modules to cover unused ways, M32 cable glands for clean and weather-resistant cable entry, and bell transformers for doorbell circuits.

Blank filler modules (18mm width) are essential for any consumer unit with unused ways — they prevent access to live busbars and give the finished installation a clean, professional appearance. We recommend ordering two additional blanks per consumer unit as a standard practice.

These accessories are automatically shown as recommended add-ons on all Terelec consumer unit product pages.
