Legrand Lighting protection

Legrand Lighting Protection – Safeguard Electrical Systems from Transients

When you’re specifying protection for lighting installations, emergency systems, data centres or commercial buildings, the Legrand lighting protection category gives you the backbone: lightning arresters, surge protective devices (SPDs), grounding and bonding systems. According to Legrand’s technical guide on SPDs, the range is designed to handle direct and indirect lightning effects across all types of installations
For procurement and design teams: adopting Legrand for your over-voltage and grounding protection means you centralise documentation, unify spares management and mitigate risk of equipment downtime after surges.

Legrand Surge Protection Devices – Primary Line Defence Against Over-Voltage

The Legrand surge protection devices (SPDs) cover type 1, type 2 and type 3 protection modules for service entrances, distribution boards and branch circuits. Their solutions include self-protected modules, plug-in replacement units, signalling contacts and wide voltage/phase compatibility.
Product example: Legrand Surge Protective Device Ex9UE3‑10 275 — a core SPD module you might choose for a main distribution board.
From an engineering viewpoint: check discharge current capacity (I imp or I max), protection voltage level UpU_pUp​, coordination with upstream fusing and earthing conductor length (50 cm rule) as noted in the Legrand guide
Tip: place SPDs as close as possible to supply entry to minimise surge path impedance and maximise protection.

Legrand Lightning Arresters & Grounding Systems – Structural Protection & Earthing

Beyond SPDs you need the infrastructure: the Legrand lightning arresters and grounding systems categories. Legrand’s SPD manual explains indirect lightning effects, rise in earth potential and importance of correct earthing
While Legrand may not label all devices “lightning arrester”, their SPD strategy includes the role of earthing and bonding systems. For procurement: ensure compatibility between arresters (if used), SPDs and earth termination network; ensure bonding loop resistance and conductor sizing meet the standard (IEC 62305 / EN 62305).
Choosing Legrand grounding-compatible devices means the earthing network and surge protection modules are engineered for each other, reducing mismatched components and simplifying inspections.

Legrand SPD Modules – Maintenance, Signalling & Replacement Capabilities

Within the SPD category, the Legrand SPD modules sub-category gives you plug-in or replaceable elements, status indication (green/OK or orange/replace), remote signalling contacts for monitoring. For example: Legrand datasheet lists replacement modules with LED indicators for T2/20 kA or T2/40 kA modules
In practical facility management: when you specify modules from Legrand you get consistent formats, compatibility with switchboard mounting, and pre-planned spare modules for lifecycle servicing.

Buyer Checklist & Specifier Guidance

  • Surge current capacity & type selection: Determine whether you need Type 1 (for buildings with external lightning protection) or Type 2/3 for indoor distribution. Legrand’s guide gives flow-capacity levels.
  • Earthing & bonding compatibility: Ensure that the SPD or arrester is connected via a suitably sized protective conductor to the main earth, minimising loop impedance as Legrand recommends.
  • Coordination with upstream protection: Use the correct protection (fuse or MCB) upstream of SPD as referenced in Legrand table of recommended protection
  • Monitoring & maintenance: Choose modules with status indication or remote signalling to schedule replacement—Legrand provides plug-in modules for this.
  • Standardisation & brand ecosystem: Using Legrand for SPDs and associated earthing components means you align with one vendor, simplifying spares, service and warranty.
  • Common mistakes to avoid: Installing an SPD far from the supply entry or with long earth conductor defeats effectiveness; mixing brands leads to mismatched performance; ignoring earthing/resonance path (e.g., >10 m cable runs) increases risk.
