L’appareil est monté sur rail DIN. On note un très léger jeu une fois en place, mais cela n’a aucun impact sur la tenue ni sur le fonctionnement du matériel. La notice est en anglais, toutefois les schémas techniques sont clairs et parfaitement exploitables pour toute personne disposant des compétences nécessaires. Le montage a été réalisé en dérivation (en parallèle), avec un raccordement sur le câble de terre du tableau principal, l’ensemble étant protégé en amont par un interrupteur différentiel et un parafoudre de type 2, conformément à la réglementation. Installé depuis environ 15 jours, le dispositif fonctionne normalement à ce jour. Concernant l’efficacité face à une surtension, il est évidemment difficile de se prononcer tant que le matériel n’a pas été confronté à ce type d’événement. Si cela devait se produire, je n’hésiterai pas à mettre à jour cet avis. Produit sérieux, conforme à la description et adapté à ce type d’application. ## Frequently Bought Together - DEWIN 2P Arrester Device, Household Surge Protector 10kA-20kA 420V AC Surge Protective Low Voltage Arrester Device 35mm DIN Rail Mounting - Schneider Electric Easy9 - MCB Miniature Circuit Breaker, 1 Pole, Type B, 6kA Breaking Capacity, 3A, 230V, EZ9F16103 - DIN Rail Enclosure, Consumer Unit Box IP65 Waterproof, DIN Rail Box 5 Module, With 4 Terminals, 2 Connectors, Suitable for Outdoor Gardens, Farms, Charging Stations, Wet Rooms --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/596919103-2p-arrester-device-10ka-20ka-420v-ac-house-surge-protective](https://www.desertcart.hr/products/596919103-2p-arrester-device-10ka-20ka-420v-ac-house-surge-protective) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-23*
