Schneider R9R51263 | Residual current circuit breaker (RCCB), Resi9, 2P, 63A, AC type, 30mA

This is a Resi9 RCCB residual current circuit breaker (RCCB). It is a 2P circuit breaker with In rated current of 63A, AC type protection class and a 30mA earth leakage sensitivity. This product protects against electrical shock by direct or indirect contact and fire hazards. As an high sensitivity residual current circuit breaker, it is recommended for all power sockets. It is also compulsory for all equipment in bathrooms, outdoors. The Resi9 is targeted to the residential market for individual and collective buildings. This product is compliant with EN/IEC 61008-2-1 standard. The (Inc/IΔc) conditional rated short circuit current is 6000 A. The (Im/IΔm) rated making and breaking capacity is 630A. The electrical endurance is up to 10000 cycles. The mechanical endurance is up to 20000 cycles. The Ue operational voltage is 230VAC. It is DIN rail mountable. The width in 9mm pitches is 4. The product colour is white (RAL9003). The dimensions are (W) 36mm x (H) 81mm x (D) 73mm. It has an IP20 degree of protection. It becomes IP40 once in modular enclosure according to IEC/EN 60529 standard. The operating temperature is from -5°C to 40°C. The storage temperature is from -40°C to 80°C.


Residual Current Circuit Breakers (RCCBs) play a crucial role in electrical safety, particularly in residential and commercial settings. Understanding their features, specifications, and installation process is essential for ensuring a safe electrical environment.

Schneider R9R51263

Schneider R9R51263 is a specific model of RCCB designed to provide effective protection against electrical faults. It belongs to the Resi9 series, offering reliable performance and safety features.

How RCCBs Work

RCCBs monitor the imbalance of electrical currents between the live and neutral wires. When an imbalance occurs, indicating a leakage or fault, the RCCB quickly trips, cutting off the power supply and preventing potential electrical hazards such as electric shocks or fires.

Types of RCCBs

There are different types of RCCBs based on their operational characteristics, including AC type, DC type, and selective RCCBs. Understanding these types helps in choosing the right one for specific applications.

Importance in Safety

RCCBs are indispensable for electrical safety as they provide protection against electric shocks, fire hazards, and equipment damage. Their ability to detect even small leakages ensures a high level of safety.

Installation Process

Installing an RCCB involves several steps such as identifying the electrical panel, switching off the power, connecting the RCCB in the circuit, and testing its functionality. Professional installation is recommended for accuracy and safety.

Maintenance Tips

Regular maintenance of RCCBs is essential to ensure they function correctly when needed. This includes periodic testing, checking for physical damage, and promptly replacing any faulty units.

Common FAQs

  1. What is the difference between an RCCB and an MCB?
    • An RCCB monitors current imbalances, while an MCB (Miniature Circuit Breaker) protects against overloads and short circuits.
  2. Do RCCBs need to be reset after tripping?
    • Yes, after an RCCB trips due to a fault, it needs to be manually reset to restore power.
  3. Can RCCBs be installed outdoors?
    • Yes, there are weatherproof RCCB models designed for outdoor installations.
  4. What is the typical lifespan of an RCCB?
    • RCCBs have a long lifespan, often lasting over a decade with proper maintenance.
  5. Are RCCBs mandatory in all electrical installations?
    • Regulations may vary by location, but RCCBs are generally recommended for enhanced safety in modern electrical systems.
