Description
Product Overview
The VAULTEX Arc Flash Suit – ATPV 40 CAL is a complete protective clothing system that provides full-body coverage against arc flash hazards. The suit is designed to protect critical areas of the body including the head, face, torso, arms, and legs.
A standard arc flash suit kit usually includes:
-
Arc-rated protective hood with integrated face shield
-
Flame-resistant coat or jacket
-
Arc-rated bib overalls or trousers
-
Storage bag or carrying case
These components work together to provide comprehensive protection against the intense heat and thermal energy generated during an electrical arc fault.
The Vaultex arc flash suit is constructed using flame-resistant multi-layer fabrics, which act as insulation barriers that reduce heat transfer to the wearer’s skin. This layered design significantly reduces the risk of second- or third-degree burns during an arc flash event.
Arc Flash Protection Technology
Arc flash incidents can generate temperatures exceeding 20,000°C, which is hotter than the surface of the sun. Because of this extreme thermal energy, workers operating near energized electrical equipment require specialized protective clothing.
The ATPV rating of 40 cal/cm² indicates the level of thermal energy that the garment can withstand before the wearer would receive a second-degree burn. A 40-calorie arc flash suit is designed to handle high-energy electrical incidents, making it suitable for the most hazardous electrical tasks.
PPE Category 4 suits such as this are typically required for:
-
High-voltage electrical switching
-
Substation maintenance work
-
Electrical panel operations
-
Transformer servicing
-
Industrial power system maintenance
Arc flash suits with this level of protection are specifically engineered to provide maximum insulation against thermal energy and molten metal particles generated during electrical faults.
Materials and Fabric Construction
The Vaultex arc flash suit is constructed from flame-resistant (FR) fabrics designed to resist ignition and prevent flame spread. These materials are either inherently flame-resistant or chemically treated to maintain their protective properties even after repeated washing.
Typical material features include:
-
Multi-layer arc-rated FR fabric construction
-
Heat and flame-resistant textile composition
-
Durable reinforced stitching for extended service life
-
High insulation performance against thermal energy
The fabric structure helps maintain the integrity of the garment during arc flash exposure while reducing heat transfer to the skin.
Additionally, the suit is designed to remain lightweight compared to traditional arc suits, which improves worker mobility and reduces fatigue during long operations.
Hood and Face Protection
One of the most important components of an arc flash suit is the protective hood and face shield. The Vaultex arc flash hood is designed with a large transparent viewing window made from polycarbonate material that provides clear visibility while protecting the face and eyes from thermal radiation and flying debris.
Key features of the hood include:
-
Integrated hard hat support system
-
Anti-fog and scratch-resistant face shield
-
Wide viewing area for improved visibility
-
Full head and neck coverage
The face shield protects against both thermal energy and arc flash light, which can cause serious eye damage without proper protection.

Safety Standards and Certifications
Arc flash suits are required to meet strict international safety standards before they can be used in industrial workplaces.
The Vaultex arc flash suit is designed to comply with standards such as:
-
NFPA 70E – Electrical safety in the workplace
-
ASTM F1506 – Flame-resistant clothing for electrical workers
-
ASTM F1959 – Arc rating testing for protective fabrics
-
IEC 61482 – Protection against thermal hazards of electric arc
-
ANSI/ISEA PPE guidelines
These standards ensure that the protective clothing has been tested for arc flash resistance, flame protection, durability, and thermal insulation.
