LAPP Lighting protection

The LAPP lighting protection category delivers high-quality solutions designed to safeguard installations from electrical hazards such as lightning strikes, transient overvoltages, ground faults and electromagnetic interference. It covers key components including LAPP lighting protection, LAPP surge protection devices, LAPP lightning arresters, LAPP overvoltage protection, LAPP SPD modules, and LAPP earthing systems. Whether you are protecting outdoor lighting infrastructure, industrial power distribution, building services or data centres, this brand category provides the mechanical and electrical safety layer essential for modern installations.

Full Range of Lapp Protection Solutions

Within this category you will find:

• LAPP surge protection devices (SPDs) – units that divert or absorb transient overvoltage spikes, protecting downstream equipment.
• LAPP lightning arresters – devices which safeguard against direct or induced lightning surges entering power or signalling circuits.
• LAPP overvoltage protection – solutions for steady-state and transient overvoltage scenarios, including switching surges and induced transients.
• LAPP SPD modules – specialized modules for DIN-rail mounting, panel integration or modular installations, enabling flexible protection strategies.
• LAPP earthing systems – grounding and potential-equalisation components such as earthing conductors, copper straps, and EMC grounding accessories (see LAPP’s “EMC and grounding” range)
• LAPP lighting protection – umbrella term covering the bundling of these protective measures in lighting circuits, public-lighting networks, façade lighting, emergency/egress lighting and building services.

By specifying the full LAPP protection ecosystem, you ensure consistent compatibility, single-brand documentation and coherent logistics for safety infrastructure.

Technical & Practical Insights – Surge, Lightning & Earthing Protection

Surge Protection Devices (SPDs)

Transient overvoltage events (e.g., lightning-induced surges or switching surges) can cause extensive damage to equipment. SPDs are designed to limit the voltage reaching protected circuits by diverting excess energy to ground.
Key design classifications include:

• Type 1 SPDs – installed at the service entrance to protect against high-energy surges (10/350 µs waveform
• Type 2 SPDs – for installation downstream (branch/distribution) to handle residual surges (8/20 µs waveform) 
  Considerations during installation: keeping connection leads short (<1 m ideally), selecting earth conductor with adequate cross section, avoiding coiled wiring.

Lightning Arresters & Overvoltage Protection

While SPDs handle transients, lightning arresters specifically deal with direct or near-direct lightning strikes, or induced high-voltage pulses. A lightning arrester typically has a high-voltage line terminal and a ground terminal and diverts high-voltage impulses to earth.
For infrastructure installations (lighting masts, public-lighting, façades) where risk of lightning is elevated, combining an arrester with upstream SPDs forms a layered protection approach.
For example: installations requiring compliance with standards such as NFPA 780 (USA) or equivalent may use SPDs rated UL 1449 or Type4CA.

Earthing & Grounding Systems

Effective lightning and surge protection depends on a low-impedance path to earth. LAPP’s earthing system products support this: high-flexibility copper earthing cables (e.g., ESUY series) for grounding and potential equalisation.
It’s crucial that the protective devices share the same earthing reference as the rest of the installation, that lightning-protection conductors are adequately sized, and that bonding is continuous and corrosion-resistant.

Application Examples & Best Practices

• Outdoor lighting installations: Use an arrester or SPD at the supply point for lighting masts, combined with branch-panel SPDs, ensure earthing continuity and equip lighting circuits with LAPP-specified modules.
• Commercial/industrial panels: Protect main distribution boards with SPD modules, coordinate with panel devices (breakers, RCDs), ensure correct classification (Type1 at board, Type2 downstream).
• Data centre/critical infrastructure: Combine overvoltage protection (for data, signal lines) with robust earthing and bonding, and use surge modules at distribution and equipment levels.
• Emergency & safety lighting: Ensure surge protection is included for circuits powering egress and exit signage—surges in these circuits could compromise life-safety systems.

Why Choose LAPP for Lighting Protection?

• Comprehensive ecosystem: LAPP offers not only cables and installation hardware but also grounding/earthing systems and protection accessories — all from one brand.
• Engineering quality: The presence of their EMC & earthing product range shows commitment to protection infrastructure (e.g., shielding connectors, ground straps) LAPP
• Proect-ready specification: For electrical wholesalers, panel builders and installers, standardising on one brand across wiring and protection simplifies inventory and documentation.
• Future-proofing: As building installations increasingly require integrated lightning/surge protection (especially with LED lighting, EV infrastructure, smart-buildings), adopting a trusted brand like LAPP helps meet evolving norms.
• Compatibility & integration: Having protection modules designed to integrate into DIN-rail systems, panels and distribution boards eases installation and serviceability.
