Electrical equipment is a number of devices that form part of an electrical system, protecting the other devices in the system from short circuits and ensuring their safety. Low-voltage equipment is used, among other things, in the construction of low-voltage distribution systems, such as LV switchgear units and service panels. The most popular items here are isolating switch-disconnectors (with independent drive) that can be 2-, 3-, or 4-pole; fused isolating switch-disconnectors, fuse load break switches, cartridge switch-disconnectors, and cam switches.
