Advanced Residual Current Circuit Breakers with Integrated Overcurrent Protection

Advanced Residual Current Circuit Breakers with Integrated Overcurrent Protection

The Advanced Residual Current Circuit Breakers with Integrated Overcurrent Protection (RCBOs) are designed to provide maximum electrical safety and efficiency in modern installations. These advanced protection devices combine two essential functions — residual current detection and overcurrent protection — within a single compact unit. They are ideal for residential, commercial, and industrial applications where protection against electric shock, fire hazards, and equipment damage is critical.

Configuration:

The RCBOs come in various configurations with rated currents ranging from 6A to 63A, operating voltages of 230/400V AC, and rated residual operating currents of 10mA, 30mA, and 100mA. The breaking capacity can reach up to 6kA or 10kA, depending on the model. These circuit breakers are available in both 1P+N and 3P+N pole versions, ensuring compatibility with single-phase and three-phase systems. They are built using high-quality flame-retardant materials and feature advanced arc extinguishing technology to ensure long-term reliability and safety.

The integrated test button allows quick functionality checks, and the compact modular design ensures easy installation in standard DIN rail panels. Optional accessories include auxiliary contacts and alarm indicators for advanced monitoring and control.

Setup:

Installing the RCBO is straightforward. Begin by ensuring that the main power supply is turned off. Mount the breaker onto a DIN rail inside the distribution board and connect the line and neutral wires as per the labeled terminals. After securing all connections, restore power and press the TEST button to verify proper operation.

These circuit breakers offer comprehensive protection against earth leakage, short circuits, and overloads, making them an essential component of any electrical safety system. With their smart design, robust configuration, and ease of setup, they ensure reliable protection for both people and equipment in all electrical environments.
