The Lyngsøe Hi-Viz Trousers (ARC-LR4052) are arc-rated, waterproof overtrousers for outdoor switching and electrical maintenance work. Tested to IEC 61482-2 with an APC 1 (Class 1) arc rating and ATPV of 8.6 cal/cm², they give substation and utility crews combined arc flash, rain and high-visibility protection in one garment.
Lyngsøe Hi-Viz Trousers: ARC-LR4052 Class 1 Arc-Rated Overtrousers
The Lyngsøe ARC-LR4052 Hi-Viz Trousers are arc-rated, waterproof overtrousers for outdoor substation and overhead-line work. The manufacturer’s datasheet confirms an APC 1 (Class 1) rating to IEC 61482-2, with ATPV of 8.6 cal/cm² and ELIM of 7 cal/cm², in a windproof and waterproof PVC-coated fabric with reflective hi-vis taping. For switching crews working outdoors in Irish weather, arc flash and rain protection in one garment is exactly what is needed.

Published certification data for these trousers also covers EN ISO 20471 (high-visibility clothing), EN 343 (rain protection) and EN 1149-5 (electrostatic properties), which is why Lyngsøe labels the garment multinorm. Treat the arc rating as the headline figure and match it against the incident energy on your switchgear label, not against the weatherproofing claims.
- MV and LV switching outdoors in wet conditions
- Work at pole-mounted or ground-mounted equipment where rainwear is routine
- Utility, contractor and generating-station crews whose arc flash assessment permits APC 1-level PPE
They pull on over your normal work trousers using the elasticated waist; where the risk assessment calls for layered protection, wear them over arc-rated base garments rather than standard polycotton. If you are unsure what rating your panel labels demand, an arc flash study will put a cal/cm² figure on each one. For background, see what is arc flash and browse the wider arc flash protection range.
FAQs
Is APC 1 the same as Class 1?
Yes. IEC 61482-2 assigns arc performance classes, and APC 1 corresponds to the former Class 1 designation. Here the manufacturer quotes ATPV of 8.6 cal/cm² and ELIM of 7 cal/cm², so check your incident energy label against those figures rather than the class label alone.
Are these worn as overtrousers?
Yes. They are pull-on waterproof overtrousers with an elasticated waist and press stud adjustment at the ankles, intended to be worn over work trousers. Choose the size accordingly and keep the arc rating of whatever you wear underneath in mind.
