The X-Series earmuffs are 3M"s latest advancement in hearing conservation. New technologies in comfort, design and protection all come together in this groundbreaking earmuff line. The X2A is a lightweight, lower-profile earmuff designed for protection against low-to-moderate level industrial noise and other loud sounds. It features an electrically insulated wire headband, often referred to as "dielectric". The X-series (over-the-head) headband version is electrically insulated - sometimes referred to as "dielectric". The metal components of the headband have been covered by non-conductive material for use in a low voltage electrical hazard (less than 440 V ac). As there are no applicable standards for testing ear muffs against electrical insulating properties, the product has been evaluated at an external laboratory against a modified test method based on EN397:1995. During assessment, the leakage current did not exceed 1.2mA when the external surface of the product made contact with an electrical source. The NRR may overestimate the hearing protection provided during typical use. Hearing protection solutions made innovatively easy. The 3M Peltor X series earmuffs are ideal for protection against noise arising from a wide range of applications in the workplace and leisure activity. Examples of typical applications include: metal processing, automotive, airports, construction, textile manufacturing, chemical and pharmaceutical, manufacturing, cement manufacturing, printing, woodworking, heavy engineering, foundry, steelworks, mining and quarrying.
