3M Peltor Optime III Hearing Protection Helmet
- Product Code: H540P3E
- EAN: 4046719384211
3M™ PELTOR™ Optime™ III H540P3E is a helmet-mounted earmuff designed for extremely high-noise environments such as heavy industry, infrastructure, and energy sectors. It is used where maximum attenuation and integration with safety helmets are required.
General Information
3M™ PELTOR™ Optime™ III H540P3E is a high-attenuation helmet-mounted hearing protector. Its primary functional benefit is effective noise reduction across both high and low frequencies through a double-shell design.
Suitability is determined by measured noise exposure (high to very high) and compatibility with the helmet attachment system.

Benefits and Differences Compared to Similar Products
- Higher attenuation level than Optime I and II, intended for very high-noise environments.
- Double-shell construction reduces resonance and improves high-frequency attenuation.
- Large internal cup volume reduces heat and moisture buildup during extended use.
- Helmet-mounted configuration enables full PPE integration without a headband.
Intended Use
Suitable for professionals in heavy industry, energy production, mining, and airport operations where very high noise levels are present and safety helmets are mandatory. It supports HSE requirements for continuous high-level hearing protection.
Not suitable for low or moderate noise environments where lower attenuation is sufficient. Selection should be based on measured exposure levels and helmet compatibility rather than product category alone.
