Types of differential blocks

At One-Elec, we offer a wide range of Schneider and Legrand differential blocks, suitable for various single-phase and three-phase applications. These devices are available in different classes (AC, A, B) to meet specific needs for protection against current leakage. Our products are available in a variety of ratings (25A, 40A, 63A, 125A), representing the maximum current capacity that each earth leakage switch can handle. It's important to choose the right rating according to the power of the devices in the circuit to be protected.

Need advice on choosing the right differential block for your electrical installation ? Our technical department will be happy to answer any questions you may have. Contact us via our contact form or by telephone on 02 99 53 96 30 Monday to Thursday from 8am to 5pm and Friday from 8am to 4pm for personalised assistance.
