Tranemo 5821 81 Class 1 Arc-Flash Trousers

The Tranemo 5821 81 is a pair of arc-rated hi-vis trousers for authorised persons, utility crews and electrical contractors working in or around substations and switchrooms. Made in Tera TX fabric at 260 g/m², they carry an arc rating of EBT50 9.5 cal/cm² to IEC 61482-2 Class 1, flame and heat protection to EN ISO 11612 (A1, B1, C1, F1), antistatic to EN 1149-5 and hi-visibility to EN ISO 20471 Class 1. In practice they sit as the everyday working layer of an arc flash protection wardrobe rather than a full switching suit.

Whether 9.5 cal/cm² is enough for a task is not a guess. It comes from the incident-energy figure on your arc flash study or equipment label; see what arc flash is for how that number maps onto PPE selection.

FAQs

How do I know if 9.5 cal/cm² covers my switchroom work?

Check the incident-energy figure from your arc flash study. If the calculated energy is at or below 9.5 cal/cm², this Class 1 rating meets that requirement. Where the study calculates a higher value, you need a higher-rated garment.

Are these trousers arc rated or only flame resistant?

Both. EN ISO 11612 covers flame and heat behaviour, while IEC 61482-2 Class 1 with EBT50 9.5 cal/cm² is the arc rating. For switching work it is the arc rating that addresses the thermal hazard of an arc flash specifically.

What sizes are available?

Regular leg in waist sizes 30 to 50 inches, Tall in 32 to 40 inches, and Short in 30 to 48 inches. Two colourways available: yellow/navy and yellow/grey.
