The HWD 68 fire protection boxes maintain fire resistance in EI30 - EI90 fire walls despite installed electrical installations and ensure safe, smokeproof room seals. In the event of a fire, an integrated intumescent quickly and reliably closes the installation opening and therefore prevents the transmission of flames and flue gases. This effectively ensures that lives are saved and property is protected. https://elecena.pl/product/21333184/9463-02-fire-protection-device-socket-hwd-68 2022-07-27 https://elecena.pl/product/21333184/9463-02-fire-protection-device-socket-hwd-68 2023-11-26 https://elecena.pl/product/21333184/9463-02-fire-protection-device-socket-hwd-68 2024-05-23 https://elecena.pl/product/21333184/9463-02-fire-protection-device-socket-hwd-68 2025-04-16
