SCHNEIDER A9R71425 RCCB Residual Current Circuit Breaker Type AC 4P 25A 30mA

RCD Circuit Breaker SCHNEIDER A9R71425 residual current protection device, RCCB Type AC 4P, rated 25A 30mA
The Schneider circuit breaker is a residual current circuit breaker (RCCB) in the Acti 9 iID range that is vital for electrical system safety. Designed to prevent electric shock from direct or indirect contact and prevent fires caused by earth leakage currents, it is a 4-pole (4P) type suitable for 3-phase electrical systems with a rated current of 25A and high tripping sensitivity of 30mA. It is an AC Type device and must be used in conjunction with a circuit breaker (MCB/MCCB) to protect against short circuits and overloads.

Specifications
- Fire protection and indirect contact electric shock protection
- With a 30 mA sensitivity, this device is set to trip when significant leakage current occurs, a level that helps prevent risks from wire overheating that could lead to electrical fires.
- Suitable for installation as an earth leakage protection device in main distribution boards 
- Capable of detecting pure sinusoidal AC leakage currents, which are common in standard electrical appliances
- The tripping mechanism operates independently of the supply voltage (voltage-independent, no electronic circuits), ensuring that the device trips immediately for safety upon an earth leakage current, even during low voltage or fluctuations

Applications & Usage
- Protects internal circuits in residential/commercial/light industrial buildings that require leakage current protection and reduced fire risk
- Used in systems requiring immediate power disconnection upon earth leakage (e.g., machine rooms, kitchens, water pump systems)
- Suitable for use in combination with branch breakers / MCCBs or other MCBs in control panels
