GEWISS Lighting protection

In modern electrical systems the invisible threats—transients from switching, lightning strikes, overvoltage events—can silently damage equipment long before they interrupt a system. The category of GEWISS lighting protection, covering surge protective devices (SPDs), lightning arresters, earthing accessories and related modules, is essential for any installation where reliability, compliance and long‑term equipment integrity matter. From panel rooms to exterior feeder boards, the right overvoltage protection devices stop the fault before it turns into a claim.

GEWISS Surge Protection Devices & Over‑Voltage Protection Modules

When you’re specifying protection against transient spikes and switching surges, you’ll commonly pick GEWISS surge protection devices (SPD modules) and GEWISS over‑voltage protection units. For example, the LST‑series modular SPD in the “90 AM Range” offers 1 P+N or 3 P+N layouts with discharge current ratings of 20 kA or 40 kA depending on module.
From real‑world builds: engineers choose the module based on upstream network structure, fault level, and whether future lightning risk is higher (external feeders, tall structures). Using GEWISS SPDs means you match the module width (EN 50022), rail‑mount spacing, and include end‑of‑life indicators—so maintenance is straightforward.

GEWISS Lightning Arresters & Earthing Accessories — Protection from Direct & Indirect Effects

When your installation includes exposed lines, external utility feeders, or tall structures, you have to deal not just with switching transients but with direct or indirect lightning strikes. That’s where GEWISS lightning arresters paired with GEWISS earthing accessories become part of the protection chain. By including proper earth termination, equipotential bonding and surge arresting modules you reduce risk of destructive over‑voltages across feeders, data lines or panel buses.
In practice: a site with external feeders and long cable runs will combine GEWISS SPD modules (Type 1/2) with earth‑ling protection bars, earthing kits and dedicated surge strips to serve as the first line of defence.

GEWISS SPD Modules, Transient Protection Units & Modular Protection Accessories

Within the broader category you’ll also deal with GEWISS SPD modules, GEWISS transient protection units, and related modular accessories. These are often plug‑in cartridges, extractable modules with optic end‑of‑life signal, designed to fit alongside circuit breakers on a graded busbar. For example, GEWISS offers spare cartridges for the LST system: extractable phase or neutral cartridges rated for 40 kA with indicator contacts.
From procurement: when you build a board you’ll allocate modules, spare cartridges, and linkable accessories to allow future extension. A modular system like GEWISS’s helps you avoid full board replacement when one module has reached end‑life.

Procurement and Wholesale Buying Insights

For B2B procurement teams selecting GEWISS lighting protection gear (SPDs, arresters, earthing kits), the buying logic typically includes:

• Protection level and rating: current discharge rating (e.g., 20 kA, 40 kA), number of poles, system voltage (230 V, 400 V).
• Type classification: Type 1 (direct strike), Type 2 (surge) or combined Type 1+2 modules
• Mounting format: DIN‑rail width (modules number), extractable cartridges, end‑of‑life indicator contacts for remote monitoring.
• Accessories and spare parts: spare cartridges, earthing bars, linking bars, remote contacts.
• Stock, lead‑time and brand consistency: surge protection modules are often on the critical path for boards; delays may push system commissioning.
• System standardisation: By using GEWISS across protection modules, earthing accessories and surge arresting you simplify training, documentation and spares management.

From field experience: a customised board build that includes surge protection up front—and from a reliable brand—reduces callbacks. You don’t just spec the main breaker and load, you spec what the system will see when the unexpected happens.
