Insulation safety shoes insulation class

Insulation is the process of using non-conductive materials to isolate or cover a live part, thereby protecting individuals from electric shocks. Effective insulation is one of the most fundamental and reliable methods to prevent electrical accidents. Insulated safety shoes are designed to protect your feet from electrical contact. However, if the insulating material you use does not match the voltage level it's exposed to, the insulation could break down, losing its protective properties entirely. As a result, the shoes may no longer provide any electrical protection. Therefore, it’s crucial to choose insulated safety shoes that are rated for the specific voltage you will be working with. Before selecting such footwear, it’s important to understand the insulation class and its corresponding temperature ratings.

Insulation Temperature Classes: Class A, E, B, F, H, C, N, R Maximum Allowable Temperature (°C): 105, 120, 130, 155, 180, 200, 220, 250 Temperature Rise Limit (K): 40, 50, 60, 75, 100, 125, 150, 175 Reference Operating Temperature (°C): 80, 95, 100, 120, 145, 170, 190, 210
