Description

Got it — here’s a clear, ready-to-use spec sheet and product summary for Matstar 4.0 mm² (with earth) based on standard industry practice for 4.0 mm² copper building cables. I tried to look up an official Matstar datasheet but couldn’t find a reliable online source right away — if you want I can run a deeper live search for an exact Matstar datasheet or local Kenyan distributors. For now, below is a practical, accurate product description you can use for listings, quoting, or installation guidance.

Matstar 4.0 mm² (with earth) — Product Details

Product name: Matstar 4.0 mm², copper conductor, with earth

Typical construction

• Conductor: Plain annealed copper, solid or stranded (stranded for flexible cable variants)

• Cross-sectional area: 4.0 mm² per conductor

• Configuration (common): 3 core + earth (3C + E) for 3-phase or 2+E / 1+E variants for single-phase uses — confirm the exact core-count you need when ordering

• Insulation: PVC (Polyvinyl chloride) or XLPE depending on variant

• Sheath: PVC outer sheath (sometimes labelled PVC/PVC) — suitable for fixed wiring in buildings

• Voltage rating: Common building-wire ratings are 300/500 V (some fixed wiring & single-phase) or 450/750 V for certain multicore/industrial variants — check the exact product datasheet

• Colour: Phase cores usually brown/black/grey or red/yellow/blue depending on region; earth is green/yellow (green with yellow stripe)

Electrical properties & practical ratings (typical)

• Typical recommended MCB size: 32 A MCB is commonly used with 4.0 mm² in many domestic radial/socket circuits (confirm with local wiring regs and installation method).

• Typical continuous current-carrying capacity: ~30–40 A depending on installation method, grouping, ambient temperature and whether cable is clipped, in conduit, buried etc. (final selection must use local wiring regulations / cable tables).

• Short-circuit / fault calculations: use actual system parameters and datasheet values (impedance, R @20°C) — ask your electrical engineer for final protective device selection.

Mechanical & environmental

• Operating temperature: commonly −5°C to +70°C (check product datasheet for exact limits)

• Flame retardant / low-smoke options: available in some product lines (specify if required for buildings/public places)

• Bending radius: follow manufacturer recommendations (usually several times conductor diameter)

Applications

• Radial or ring circuits to socket outlets (where permitted)

• Small motor supply and sub-distribution in buildings

• Lighting circuits (depending on load and regulations)

• Domestic and light-commercial fixed wiring

Standards & certification (what to ask supplier for)

• Ask for certificate of conformity to recognized standards (e.g., IEC, BS, or local standards), test reports, and RoHS/CE/ISO marks where applicable. Also ask for conductor resistance and insulation test values on the datasheet.

Installation notes / best practice

• Confirm whether cable is solid or stranded — stranded is easier to terminate on terminals and breakers.

• Use the correct sized ferrules or lugs and tighten to manufacturer torque.

• Use the correct MCB/MCB curve and earth-fault protection matched to cable rating.

• Avoid grouping cables without de-rating; always consult cable de-rating tables.

• If feeding heaters/cookers or long runs, check voltage drop and consider upsizing if needed.

Packaging & lengths

• Supplied on drums or coils (e.g., 100 m, 200 m rolls) — confirm with supplier.

If you’d like I can next:

• (A) Look up the official Matstar 4.0 mm² datasheet and Kenyan distributors and pull exact figures (voltage rating, conductor resistance, exact current tables) — I can search online for that.

• (B) Produce a short 60-character SEO title + 160-character meta description for a product page listing.

• (C) Create a product listing template (short spec table + features + installation notes) you can paste into your site.
