Rated Current 6-40 Residual Current Circuit Breaker with Overload Protection Curve Type D Curve Providing Electrical Fault Detection

Product Description:

The RCBO Circuit Breaker is an essential component designed to provide both residual current protection and overload protection in electrical installations. This Residual-Current-Circuit-Breaker-with-Overload-Protection combines the functions of an RCD (Residual Current Device) and an MCB (Miniature Circuit Breaker) into a single compact unit, ensuring enhanced safety and reliability for residential, commercial, and industrial electrical systems.

With a size of just 18mm in width, this RCBO is a 1P+N device, meaning it includes both a single pole and neutral connection, making it ideal for modern electrical panels where space efficiency is critical. Despite its compact form factor, it provides robust protection against earth leakage currents and overload conditions, preventing potential electrical hazards such as electric shocks, short circuits, and fires.

The RCBO is rated for a frequency of 50/60Hz, making it suitable for use in a wide range of electrical networks globally. Its rated current ranges from 6A to 40A, allowing for versatile application across various circuit requirements. Whether protecting lighting circuits, power outlets, or specialized equipment, this Residual-Current-Circuit-Breaker-with-Overload-Protection ensures that the current flowing through the circuit remains within safe limits, tripping instantaneously when abnormal conditions are detected.

One of the standout features of this RCBO is its electronic tripping mechanism. Unlike traditional thermal-magnetic breakers, the electronic tripping type provides more precise and faster response to fault conditions. This enhances the protective capabilities by reducing nuisance tripping and improving the overall reliability of the electrical system. The electronic tripping also allows for better sensitivity to residual current leakage, which is critical for preventing electric shock hazards.

The device is equipped with a transparent cover, offering clear visibility of the breaker’s status and internal components without needing to remove the cover. This design feature enhances safety during inspection and maintenance, allowing users or technicians to quickly verify whether the breaker is in the ON or OFF position and to inspect for any signs of wear or damage.

Installation is straightforward due to the standardized 18mm width, which fits neatly into most DIN rail mounting systems commonly used in electrical distribution boards. The compact size not only saves space but also simplifies wiring and reduces panel clutter, contributing to a cleaner and more organized electrical setup.

In summary, this RCBO Circuit Breaker is an indispensable Residual-Current-Circuit-Breaker-with-Overload-Protection device that delivers reliable, high-performance protection for electrical circuits. Its electronic tripping type, wide rated current range of 6A to 40A, and compatibility with 50/60Hz systems make it a versatile choice for a multitude of applications. The transparent cover enhances usability and safety, while its slim 18mm width ensures easy integration into existing electrical panels. By incorporating this RCBO into your electrical installation, you are ensuring superior protection against electrical faults and enhancing the overall safety of your electrical system.
