The Tranemo 5774 86 is a non-metal flame retardant shirt, arc rated to IEC 61482-2 Class 1 with an ATPV of 10.5 cal/cm². High-visibility sleeves, concealed plastic stud front and chest pockets make it a practical everyday layer for switchroom and substation personnel.
Tranemo 5774 86 Non-Metal FR Shirt, Class 1, 10.5 cal/cm²
The Tranemo 5774 86 is a non-metal flame retardant shirt for personnel working around energised switchgear. It is arc rated to IEC 61482-2 Class 1 with an ATPV of 10.5 cal/cm², sitting in the everyday-wear bracket for MV and LV switching tasks where a full switching suit is not required. The non-metal construction, with a concealed front closing using plastic stud fasteners, removes exposed conductive parts from the garment, a detail that matters when you are leaning into a switchboard.
Key Features
- Non-metal design with concealed front closing and plastic stud fasteners
- High-visibility fabric on the sleeves for added visibility around plant and switchrooms
- Chest pockets with flaps for secure storage
- Outback 250 fabric at 250 g/m², light enough for all-day wear
- Yellow/navy colourway, sizes XS to 4XL
Standards and Ratings
| Standard / Rating | Classification |
|---|---|
| IEC 61482-2 (arc rating) | Class 1, ATPV 10.5 cal/cm² |
| EN ISO 11612 (heat and flame) | A1+A2 B1 C1 D1 E1 F1 |
| EN ISO 11611 (welding and allied processes) | Class 1 A1+A2 |
| EN 1149-5 (electrostatic properties) | Certified |
| EN 13034 (limited chemical splash) | Type PB[6] |
That combination of certifications makes the shirt useful well beyond the substation. EN 1149-5 electrostatic protection suits ATEX-aware environments, and the EN ISO 11611 rating covers hot-work adjacent tasks. If you are unsure how arc ratings map to the incident energy on your switchgear labels, our guide on what arc flash is explains the basics, and the wider arc flash protection range covers higher incident energies where Class 1 is not enough.
Who It Is For
Authorised persons, utility crews, data-centre and pharmaceutical plant engineers, and contractors who need a certified arc-rated shirt for daily wear rather than a task-specific switching suit. Browse matching garments in our arc flash shirts and polo shirts category.
FAQs
Is 10.5 cal/cm² enough for my switchroom?
It depends on the incident energy at each location, which comes from an arc flash study or the equipment label. Class 1 with an ATPV of 10.5 cal/cm² suits many LV and MV switching tasks, but higher energy locations need higher rated garments. If you are unsure, ask us about an arc flash study.
What sizes and colours does the Tranemo 5774 86 come in?
The shirt is available in sizes XS to 4XL in a yellow/navy colourway, with high-visibility fabric on the sleeves. The fabric is Tranemo’s Outback 250 at 250 g/m².
