Schneider Acti9 RCCB 40A 4P 300mA – Reliable Fire Protection for Three-Phase Systems
Ensure dependable protection for high-load three-phase electrical systems with the Schneider Acti9 RCCB 40A 4P 300mA. Designed for industrial, commercial, and large residential applications, this Residual Current Circuit Breaker (RCCB) protects circuits against earth leakage faults, helping prevent fire hazards and safeguarding electrical installations.
This RCCB features a 40A current rating with a 4-pole (4P) configuration (3P + N), ensuring complete protection across all three phases and neutral. It is ideal for distribution boards where full circuit isolation is required for safety and maintenance.
The 300mA sensitivity is specifically designed for fire protection, detecting leakage currents caused by insulation failure or wiring faults. Unlike 30mA RCCBs (used for personal safety), this device focuses on preventing fire risks in high-load and large-scale electrical systems.
With Type AC protection, the RCCB detects sinusoidal alternating leakage currents, making it suitable for standard AC electrical systems in commercial buildings, factories, and infrastructure projects. It continuously monitors current imbalance and trips instantly when leakage is detected.
Built with Schneider’s Acti9 technology, this RCCB offers voltage-independent tripping, ensuring reliable operation even under voltage fluctuations. It supports DIN rail mounting, allowing quick and secure installation in standard electrical panels.
Manufactured as per IS/IEC 61008 standards, the device ensures durability, precision, and long service life, making it a trusted choice for professionals.
