Auriculares de protección auditiva 3M H520P3E-410-GQ para casco negro

3M™ PELTOR™ Optime™ II earmuffs (model H520P3E) are hearing protection designed for loud, demanding environments such as airports, construction sites, and agricultural or industrial work. Tested to EN 352:2020, these earmuffs provide noise reduction up to 31 dB and are available in helmet-mount form (helmet style, black) suitable for tasks including assembly, demolition, grinding, sanding, and welding.

Advantages

The Optime™ II design delivers advanced attenuation even at very low frequencies, with soft, wide cushions and ventilation channels in the sealing rings to reduce pressure, heat and moisture around the ears. Generous internal cup space and patterned hygienic foam improve comfort during extended wear. Replaceable foam cushions and inserts (hygiene kits) extend product life. Multiple attachment styles and color options are available, including helmet attachment and black finish for the H520P3E model.

How to use

Attach the earmuffs to a compatible safety helmet using the helmet-mount fittings, ensuring the cups fully cover the ears and the sealing rings contact the head evenly. Adjust the helmet fit and muff position so there are no gaps around the ear seals. Inspect cushions and inserts before use and replace worn or damaged hygiene kit components to maintain optimal attenuation. Follow the helmet and PPE manufacturer instructions when combining with other protective equipment.

Recommendations

Use these helmet-mounted earmuffs for prolonged noisy tasks where combined head protection is required. Regularly check seals and replace hygiene kit parts as needed. Confirm suitability by measuring workplace noise levels and ensuring the 31 dB attenuation meets required protection for specific tasks.
