EARMUFF PELTOR H540A

For extreme noise environments, the 3M™ PELTOR™ Optime™ III H540A sets the benchmark for high-performance hearing protection. Engineered for maximum attenuation (SLC?? 33 dB, Class 5), these earmuffs are ideal for the most demanding industrial conditions such as airports, marine engine rooms, power stations, mining sites, and heavy manufacturing.

Utilising double-casing technology, the Optime™ III minimises resonance within the earcup housing to deliver exceptional high-frequency noise attenuation. The large internal cup space helps reduce heat and moisture build-up, while the soft, wide foam cushions lower contact pressure, ensuring superior comfort and wearer compliance over long shifts.

Built from tough dual-moulded ABS, these earmuffs are designed for durability in harsh environments. Replaceable hygiene kits (cushions and inserts) make maintenance simple, extending product life and ensuring consistent performance.
