Schneider Acti9 ID K RCCB 4P 40A 30mA Type AC – A9KR11440BQ
Ensure complete electrical safety for three-phase systems with the Schneider Acti9 ID K RCCB A9KR11440BQ, designed for residential, commercial, and industrial applications. This Residual Current Circuit Breaker (RCCB) provides reliable protection against earth leakage and electric shock, making it an essential safety component in modern electrical installations.
This model features a 40A current rating with 4-pole (4P) configuration (3P + N), ensuring protection across all three phases and neutral. It is ideal for three-phase distribution boards and systems where full circuit isolation is required for safety and maintenance.
The 30mA sensitivity offers high-level personal protection, instantly disconnecting the power supply when leakage current is detected. This helps prevent electric shock and reduces the risk of electrical accidents.
With Type AC protection, the RCCB detects sinusoidal alternating leakage currents, making it suitable for standard AC electrical systems in homes, offices, and industrial setups. It continuously monitors current imbalance and trips immediately during fault conditions.
Designed under Schneider’s Acti9 ID K range, this RCCB supports DIN rail mounting for quick and secure installation in electrical panels. It also offers voltage-independent tripping, ensuring reliable operation even during voltage fluctuations.
Built in compliance with IS/IEC 61008 standards, this device ensures durability, consistent performance, and long service life—making it a trusted choice for professionals across India.
