Description

What is RCBO?
A Residual Current Breaker with Overload Protection (RCBO) is a critical electrical safety device that combines the functionality of a Residual Current Device (RCD) and a Miniature Circuit Breaker (MCB). It provides dual protection against residual currents (to prevent electric shocks) and overcurrents (to protect against overloads and short circuits).
The GYR9NE-B is a high-performance Type B RCBO designed for modern electrical systems. With high sensitivity, robust anti-electromagnetic interference, and excellent shock resistance, it ensures reliable protection across various residual current types.
Product Benefits:
- Enhanced Safety: Quickly disconnects faulty power sources to prevent electric shocks and fire risks.
- Space-Saving Design: Integrates RCD and MCB functionalities, reducing installation space and costs.
- Compliance with Standards: Meets international standards (IEC, GB) for reliability and market acceptance.
- Versatility: Suitable for both AC and DC applications, ideal for modern mixed-load systems.
- Durability: High-quality materials ensure long-term performance in harsh environments.
Comparison with Other Types:
Type A RCBO: Suitable for sinusoidal AC currents but limited in detecting pulsating DC or smooth DC currents.
Type B RCBO (GYR9NE-B): Offers broader protection, including sinusoidal AC, pulsating DC, and smooth DC currents, making it ideal for applications with inverters, variable speed drives, or other non-sinusoidal loads.
Applications:
The GEYA GYR9NE-B is suitable for a wide range of applications, including:
- Industrial Settings: Protects factories and heavy equipment.
- Commercial Buildings: Ensures electrical safety in offices and commercial facilities.
- High-Rise Buildings: Provides reliable residual current and overload protection.
- Residential Homes: Enhances electrical safety for households.
- Photovoltaic Systems: Ideal for applications with DC components due to its Type B characteristics.
