What is an RCBO device?

RCBO is short for Residual Current Circuit Breaker with Overcurrent Protection. An RCBO is a crucial component in electrical systems. They provide both residual current protection and overcurrent protection. It is a circuit breaker installed in your consumer board or fuse board. As a dual-function electrical protection solution, the RCBO Protection Device has become indispensable in modern residential, commercial, and industrial settings, and Zhejiang C&J Electrical co., ltd. (hereinafter referred to as C&J Electrical) has launched the CJRO1 series RCBO to redefine safety and efficiency in electrical protection.

Unlike standalone RCDs (Residual Current Devices) that only handle current imbalances or circuit breakers focused solely on overloads and short circuits, an RCBO integrates both protections into one compact unit. This integration eliminates the need for separate installations, simplifies electrical panel layout, and ensures comprehensive safeguarding—preventing electric shocks caused by residual current while shielding circuits and equipment from damage due to excessive current or short circuits. For users seeking reliable, all-in-one protection, the RCBO Protection Device is the optimal choice, and C&J Electrical’s CJRO1 series takes this performance to the next level.

The CJRO1 RCBO from C&J Electrical boasts impressive core specifications: a breaking capacity of 6kA, ensuring it can safely interrupt high fault currents to avoid electrical hazards. Its shell is crafted from PA66 flame-retardant material, which not only offers excellent heat resistance and durability but also enhances fire safety by preventing flame spread. A key design highlight is the visual window, allowing users to check the contact position without physical operation—eliminating potential risks during inspection and ensuring convenient status monitoring.

Space efficiency is another major advantage of the CJRO1 series. The 1P+N model is only 18mm wide, reducing volume by 30%-50% compared to traditional residual current protectors. This compact size significantly saves cabinet space, lowers installation and cabinet costs, and makes it ideal for electrical panels with limited room. Equipped with 30mA residual current protection, the device is highly sensitive to leakage currents, triggering an immediate power cut to prevent electric shocks—providing reliable safety for families and workers.

In terms of performance stability, the CJRO1 RCBO excels with a mechanical and electrical durability of up to 4000 cycles, ensuring long-term reliable operation even in high-frequency usage scenarios. It offers two leakage current protection types: AC type, which guards against alternating current leakage, and A type, which provides comprehensive protection against both alternating current and pulsating direct current leakage—catering to diverse application requirements. Additionally, the device integrates overload protection, short circuit protection, and residual current protection, forming a three-in-one safety barrier that meets the highest safety standards.

To meet global market demands, the CJRO1 RCBO has passed rigorous testing and obtained multiple international safety certifications, including CE, CB, UKCA, SAA, and TUV. These certifications validate its compliance with global electrical safety norms, making it suitable for use in various countries and regions. Moreover, C&J Electrical offers customization options for the handle and clip colors, allowing users to personalize their RCBO devices—adding a touch of uniqueness to home or commercial electrical systems while maintaining top-tier protection.

As a trusted manufacturer of electrical protection products, C&J Electrical is committed to delivering high-quality, innovative solutions that prioritize safety, efficiency, and user experience. The CJRO1 series RCBO Protection Device embodies this commitment, combining advanced technology, compact design, and reliable performance to meet the diverse needs of modern electrical systems.
