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.


Overview of Schneider R9R51225

The Schneider R9R51225 is a high-quality Residual Current Circuit Breaker designed to protect against electrical faults by monitoring the balance between incoming and outgoing currents.

Importance of RCCBs

Safety in Electrical Circuits

RCCBs play a crucial role in safeguarding individuals and property from electric shocks and fire hazards caused by ground faults or leakages.


2P, 25A, AC Type, 30mA

This model comes with 2 poles, a 25A rating, operates on AC type circuits, and has a sensitivity of 30mA, ensuring effective protection.

Working Principle

Protecting Against Electrical Faults

The RCCB detects any imbalance in the currents flowing through the live and neutral wires, tripping the circuit to prevent potential harm.


Guidelines for Setting Up

It’s essential to follow manufacturer guidelines and consult with professionals for correct installation to ensure optimal performance and safety.

Types of RCCBs

Differentiating AC and DC Types

RCCBs are available in AC and DC types, each serving specific purposes based on the electrical system they are used in.


Enhanced Safety and Reliability

The R9R51225 offers enhanced safety by quickly disconnecting the circuit in case of faults, thereby reducing the risk of accidents and damage.


Residential and Commercial Usage

These RCCBs are suitable for a wide range of applications, including homes, offices, industries, and public spaces, contributing to a safer environment.


Tips for Longevity

Regular inspection, testing, and maintenance of RCCBs ensure their proper functioning over time, extending their lifespan and reliability.


In conclusion, the Schneider R9R51225 Residual Current Circuit Breaker is an indispensable device for maintaining electrical safety. Its advanced features, ease of installation, and wide-ranging applications make it a preferred choice for both residential and commercial setups.


  1. What is the purpose of an RCCB? An RCCB is designed to protect against electric shocks and fire hazards by monitoring electrical imbalances.
  2. How does an RCCB differ from an MCB? An RCCB detects ground faults and leakages, while an MCB (Miniature Circuit Breaker) protects against overloads and short circuits.
  3. Can an RCCB protect against lightning strikes? While RCCBs provide some protection, additional measures such as surge protectors are recommended for lightning strikes.
  4. What is the lifespan of an RCCB? With proper maintenance, RCCBs can last for many years, ensuring long-term electrical safety.
  5. Are RCCBs mandatory in electrical installations? Depending on local regulations and safety standards, RCCBs are often mandated in modern electrical installations for added safety measures.
