Description

This product description covers both RCCBs (Residual Current Circuit Breakers) and RCBOs (Residual Current Circuit Breakers with Overcurrent Protection), highlighting their key features, benefits, and applications.

What are RCCBs and RCBOs?

RCCBs and RCBOs are essential safety devices designed to protect people and property from the dangers of electric shock and fire caused by electrical faults. They are crucial components in modern electrical installations, offering superior protection compared to traditional fuses or circuit breakers alone.

RCCB (Residual Current Circuit Breaker):

• Function: An RCCB detects imbalances in the current flowing in the live and neutral conductors of an electrical circuit. Even a small leakage current, such as that caused by a fault to earth, is enough to trip the RCCB, quickly disconnecting the power and preventing electric shock.
• Protection: Primarily protects against electric shock.
• Overcurrent Protection: Does not provide overcurrent protection (overload or short-circuit protection). Must be used in conjunction with a separate circuit breaker or fuse.
• Applications: Used in conjunction with MCBs (Miniature Circuit Breakers) to provide comprehensive protection in circuits where electric shock is a primary concern, such as bathrooms, kitchens, and outdoor areas.

RCBO (Residual Current Circuit Breaker with Overcurrent Protection):

• Function: An RCBO combines the functions of an RCCB and a miniature circuit breaker (MCB) in a single unit. It detects current imbalances (like an RCCB) and also protects against overloads and short circuits (like an MCB).
• Protection: Protects against electric shock, overloads, and short circuits. Offers a more compact and cost-effective solution compared to separate RCCB and MCB installations.
• Overcurrent Protection: Provides built-in overload and short-circuit protection.
• Applications: Ideal for individual circuits in residential, commercial, and industrial settings where both electric shock and overcurrent protection are required. A versatile and widely used safety device.

Key Features (applicable to both RCCBs and RCBOs):

• High Sensitivity: Trip quickly even with small leakage currents, minimizing the risk of electric shock.
• Reliable Operation: Ensures consistent and dependable protection.
• Easy Installation: Designed for simple and straightforward installation in standard distribution boards.
• Clear Indication: Provides clear visual indication of a tripped state.
• Various Ratings: Available in a range of current ratings (e.g., 6A, 10A, 16A, 20A, 32A) and tripping sensitivities (e.g., 30mA). Choose the appropriate rating based on the circuit's requirements.
• Compliance with Standards: Meets or exceeds all relevant international safety standards (e.g., IEC 61008-1, IEC 61009-1).
