Arc® 43

Product catalog summary

Overview: The document provides detailed information on Lakeland's Arc Flash Protection garments, specifically the Arc® 43 line, designed to protect against high-level arc flash heat incidents. It includes specifications, standards, and guidelines for selecting appropriate protective clothing.

Specifications:

The Arc® 43 suit is made of a triple-layer fabric with an Arc Thermal Protective Value (ATPV) of up to 43 cal/cm².
The fabric composition is 48% modacrylic, 37% cellulosic, and 15% para-aramid, with a total weight of 720gsm.
The suit includes a hood with a 40 cal-rated arc visor, jacket, bib & brace pants, gloves, and boots, all stored in a carry case.
Seams are reinforced with a five-needle safety stitch using FR/Aramid thread.

Physical Properties:

Tensile Strength: 970 N (md), 630 N (cd) - Pass
Trapezoidal Tear: 29 N (md), 26 N (cd) - Pass
Seam Strength: 355 N - Pass

Flame, Heat, and Arc Thermal Protective Performance:

Flame Spread: ISO 15020-2000 A1 - Pass
Heat Resistance: ISO 17492 - Pass
Convective Heat: 5.2 sec (ISO 9151:1995) - B1
Radiant Heat: 12.2 sec (ISO 6942:2002) - C1
Arc Protection: Box Method (EN 61482-1-2) - 7 Ka, ATPV - 42 cal/cm²

Understanding Arc Flash Protection:

Arc Flash occurs when an electrical charge jumps between terminals, causing intense heat, explosive force, and potential electrical shock.
Protective garments are primarily designed to protect against heat hazards.

Selection Process:

Assess: Determine the incident heat energy level using calculations based on circuit voltage and equipment class.
Identify: Determine the required ATPV or Hazard Risk Category (HRC) based on the assessed heat energy level.
Select: Choose garments with the appropriate HRC or ATPV rating. Layering garments can increase protection levels.

Standards and Classifications:

ATPV is measured according to EN 61482-2-1 or ASTM F1959, indicating the heat energy level protection value.
HRC defines four classes of garments based on ATPV: HRC 1 (4 cal/cm²), HRC 2 (8 cal/cm²), HRC 3 (24 cal/cm²), HRC 4 (40 cal/cm²).
EN 61482-2-2 measures arc protection for low energy levels using the 'arc-in-a-box' method, identifying two classes: Class 1 (up to 4Ka) and Class 2 (up to 7Ka).

Protect Your People Understanding Arc Flash Protection What is Arc Flash? What are hazards of Arc Flash? How do you select an Arc Flash protective garment? Arc Flash occurs when an electrical charge jumps between two terminals or from a terminal to earth Arc Flash protective garments are primarily designed to protect against the heat hazard of electric arc and not the electrical shock or concussive force. Arc Flash incidents can occur in any industrial situation where a fault in a circuit occurs In an instant an arc flash incident can generate enormous amounts of heat energy and temperatures...
