The X-series earmuffs are 3 's latest advancement in Hearing conservación. New technologies in Comfort, diseño and protección all come together in this groundbreaking Earmuff Line. The X5 A earmuffs offer the highest NRR (31 dB) for an Earmuff on the market which makes them ideal for very high Noise situaciones. The high atenuación delivered by X5 A earmuffs is posible as a result of a combination of Advanced tecnologías including: newly designed spacers, specially Formulated Earcup revestimientos and innovative Foam contained in the cushions. The X-series (over-the-head) Headband versión is Electrically aislados - 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 aplicable Estándar 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 1.2 mA when the External superficie of the product Made contact with an electrical Fuente. The NRR may overestimate the Hearing Protection provided during typical use. Hearing Protección soluciones Made innovatively Easy.
