Legrand DX3 406520 63A Four Pole Isolator Switch

Company Cat No: 4065 20

A Legrand Four Pole Isolator is a reliable electrical switch designed to disconnect all four poles—three-phase (R, Y, B) and neutral—ensuring complete isolation of a circuit. Unlike MCBs, which trip automatically during a short circuit, an isolator must be operated manually, making it ideal for safe maintenance and load management. These isolators are commonly used in three-phase electrical systems for industrial, commercial, and high-power residential applications. You can buy online from trusted retailers like BestofElectricals.com, where you’ll find a range of Legrand Four Pole Isolators designed for durability, safety, and compliance with electrical standards.
