Product Overview

Residual Current Breaker with Over-Current protection (RCBO) is a critical safety device combining the functions of a Residual Current Device (RCD) and a Mini Circuit Breaker (MCB). It protects both personnel and equipment by detecting leakage currents, overloads, and short circuits.

Core Protection Features

The RCBO monitors current flow balance between live and neutral wires. In the event of an imbalance caused by leakage (e.g., faulty appliance or ground fault), the device trips instantly to prevent electric shock and potential fire hazards.

Key Product Benefits

  • Advanced Air Circulation: Specialized channels form tunnels between adjacent poles, ensuring efficient cooling during operation.
  • Bi-connect Termination: Supports simultaneous use of Busbar and cables in the same terminal for versatile and reliable connections.
  • Stable DIN Rail Mounting: Features a two-step snapping mechanism for secure installation on standard 35mm DIN Rails.
  • High Breaking Capacity: Rated breaking capacity up to 6000A for enhanced safety.
