  • Product description

    Membrane cable entry plate with cones | for 216×84 mm cut-out | 6× Ø13–28 + 18× Ø6–13 + 4× Ø3–11 mm | grey | IP65 | HT Hi Tech Polymers | HTKC-28

    HTKC-28 is a TPE-SEBS elastomer plate for a 216×84 mm cut-out with as many as six large cones Ø13–28 mm. Next to them are 18 cones Ø6–13 mm and 4 cones Ø3–11 mm. The cone tip is cut to the cable's outer diameter and each cable is sealed individually.

    Key point:
    Many 216×84 mm plates have only one or two entries for a thick cable. HTKC-28 is designed for boards that send out several power cables – to other boards, motors, heat pumps or charging points. Six cones up to Ø28 mm allow all of them to enter through one cut-out.

    How it works

    A 216×84 mm opening is cut in the board wall, Ø10 mm holes are drilled (spacing 193 × 62 mm) and the plate is screwed on.

    Large cones are cut for thick cables, small ones for thin cables; each is cut at a step slightly smaller than the cable's outer diameter.

    Power and control cables are sealed in one plate (IP65), unused cones stay closed.

    Why choose HTKC-28?
    It fits up to six thick cables plus 22 medium and thin ones in one standard cut-out – without extra large glands with nuts.

    Main functions

    • 6 cones Ø13–28 mm – for supply, sub-feeder and motor cables
    • 18 cones Ø6–13 mm – for circuit and control cables
    • 4 cones Ø3–11 mm – for thin signal or communication cables
    • Wide ranges – one cone suits cables of various thicknesses
    • Closed spare cones – stay sealed until used

    Where is it used?

    • Main and distribution boards in buildings feeding other boards
    • Industrial distribution cabinets with motor cables
    • Supply boards for EV charging points
    • Heat pump and boiler room power boards
    • Construction site distribution cabinets
    • Outdoor lighting and infrastructure boards

    Use by need

    For designers.
    When several power cables leave a board, a single cut-out solution simplifies enclosure selection and drawings.
    For electrical contractors.
    Six thick cables go in without separate large glands or extra holes in the wall.
    For plant energy engineers.
    When a new sub-feeder is added, a free large cone lets the cable in without dismantling the existing entry.

    Practical application

    If a building distribution board has an incoming cable Ø26 mm, four sub-feeder cables Ø18–22 mm to floor boards, 12 circuit cables Ø10 mm and 2 alarm cables Ø5 mm, HTKC-28 takes them all and one large cone is still left in reserve.

    Pros

    • Six cones for thick cables up to Ø28 mm
    • Wide ranges – Ø13–28 and Ø3–11 mm
    • Operating temperature −40…+130 °C
    • IP65, for indoor and outdoor use
    • Halogen-free, oil-splash-resistant material

    Cons / limitations

    • Not for cables thicker than Ø28 mm – choose HTX-23 (up to Ø48 mm) or HTC-3
    • Fewer entries for small cables than HTKC-50 or HTKC-43
    • Does not provide strain relief – thick cables must be secured inside the board
    • Not a fire barrier

    Safety and installation notes

    • All work in the board only with the power off and absence of voltage verified.
    • Remove swarf after cutting and drilling.
    • Thick cables are stiff – secure them inside the board so their weight and bending do not deform the cone.
    • Cut the cone at a step slightly smaller than the cable's outer diameter.

    Quick selection guide

    Cut-out 216×84 mm
    6 × Ø13–28 mm
    18 × Ø6–13 + 4 × Ø3–11 mm
    IP65, −40…+130 °C
    Suitable when you need:
    • several thick power cables through one cut-out
    • circuit and signal cables in the same plate
    • spare capacity for future sub-feeders
    Check before use:
    • the outer diameter of the thickest cable – no more than Ø28 mm
    • the number of thick cables – no more than six
    • whether thick cables can be secured inside the board
    Important reminder: HTKC-28 seals the entry (IP65), but does not carry the weight and pulling forces of thick cables and is not a fire-stop seal – fix the cables separately.

    FAQ

    How many thick cables can enter through HTKC-28?
    Up to six cables with an outer diameter of Ø13–28 mm.
    Is it suitable for a Ø30 mm cable?
    No, the largest cones are for up to Ø28 mm; for thicker cables choose HTX-23.
    What are the 4 cones Ø3–11 mm for?
    For thin signal, sensor or communication cables.
    Can it be fitted into the same cut-out as HTC-50?
    Yes, all plates of this series are for a 216×84 mm cut-out with the same fixing holes.
    Is HTKC-28 suitable for an outdoor cabinet?
    Yes, the material is intended for outdoor use, protection IP65, operating temperature −40…+130 °C.
    Do thick cables need to be secured?
    Yes, the plate does not provide strain relief, so they must be secured inside the board.
