Schneider Electric A9Z64463 - Interruttore differenziale - 1500 A - IP20 - IP40

Residual Current Circuit Breaker (RCCB) delivering reliable earth leakage protection with a 30 mA sensitivity, rated for 63 A across four poles. The Acti9 iID A9Z64463 safeguards circuits against insulation faults, reducing the risk of electric shock and fire. Its Type A tripping characteristic handles alternating and pulsating direct residual currents, making it suitable for modern installations with electronic loads. Designed for DIN rail mounting, this device fits standard distribution boards and offers IP20 protection (IP40 when enclosed).

Advantages

This RCCB ensures continuous protection with a rated conditional short-circuit current of 10 kA and a wide operating temperature range from -25 °C to 60 °C. The 30 mA sensitivity is ideal for personal protection, while the four-pole configuration supports three-phase networks. Its compact design and robust construction provide long-term reliability, backed by electrical and mechanical durability of 20,000 cycles. Compliance with EN/IEC 61008-1 guarantees safety and performance.

Suitable for

• Residential distribution boards requiring earth leakage protection
