Power distribution box switches in South Africa include MCBs, RCCBs, RCBOs, and switch-disconnectors, available from leading suppliers like Schneider Electric, CEDSA, Onesto Africa, Crabtree, and Henelec.

Types of Switches and Distribution Boxes

Switch-disconnectors are designed to safely isolate electrical circuits and are available in ratings from 50 A up to 2500 A, suitable for both residential and industrial applications. Schneider Electric's ComPact INS/INV range offers reliable isolation, compatibility with MasterPact and ComPact circuit breakers, and options for remote monitoring via Smart Panels . Fuse switch-disconnectors and electronic monitoring devices provide additional protection against short circuits and overloads. MCBs (Miniature Circuit Breakers), RCCBs (Residual Current Circuit Breakers), and RCBOs (Residual Current Breaker with Overcurrent protection) are commonly used in South African distribution boxes for circuit protection. These modular devices are available in single-phase and three-phase configurations, with enclosures made from plastic, steel, or stainless steel, often waterproof for outdoor or industrial use .
