3 Phase RCBO

A 3 phase RCBO protects all three live wires in a three-phase electrical system. It guards against short circuits, overloads, and earth faults. Unlike standard RCBOs, these devices are true 3-pole or 3-pole plus neutral (3P+N) types. They work well in places where strong, full-phase protection is needed.

Electricians often use them in shops, factories, and large buildings. You can install them in a TPN (three-phase) distribution board. They are a great choice for circuits that power motors, machines, or heavy equipment.

Choose a 3 phase RCBO when your job needs reliable protection across all phases. Most models also come with a 10kA breaking capacity for added safety.
