Lyngsøe Hi-Viz Bib Trousers, Class 1 (ARC-LR4059)
The Lyngsøe ARC-LR4059 is a multinorm hi-vis bib and brace trouser in an extra strong PVC quality, built for electrical work outdoors in genuinely poor weather. It is arc rated to EN 61482-2:2020, APC 1, with an ATPV of 8.6 cal/cm² and an ELIM of 7 cal/cm², so it gives you tested protection against the thermal hazards of an electric arc while keeping the rain out. For switching and maintenance work on exposed substations and overhead line sites, that combination matters.

Applications
These trousers suit authorised persons, utility crews and contractors working outdoors on MV and LV networks, substation yards and overhead line sites where wet weather and arc flash risk overlap. The bib and brace format gives extra torso coverage under a jacket, and the waterproof rating keeps the garment serviceable through a full shift in the rain. Remember that arc-rated rainwear is one layer of the system. Match the garment’s ATPV to the incident energy on your arc flash labels, and if you are unsure what your switchrooms require, our arc flash studies service will quantify it. You can read more about the hazard itself in our guide to what arc flash is, or browse the wider arc flash protection range.
FAQs
What does APC 1 mean on these trousers?
APC 1 is the arc protection class under EN 61482-2:2020, confirmed by the box test method. It means the fabric has withstood a 4 kA electric arc exposure. The ARC-LR4059 also carries an open-arc ATPV of 8.6 cal/cm², giving you two verified measures of its thermal protection.
How do I know if 8.6 cal/cm² is enough protection?
Compare the ATPV against the incident energy figure on your equipment’s arc flash label. The garment rating must meet or exceed that figure. If your site has no labels, an arc flash study will calculate incident energy at each location and tell you what PPE level you need.
