Schneider Electric R9R22225 - interruttore differenziale Resi9 1P+N 25A 30mA Tipo A

In residential and commercial electrical panels, the Schneider Electric Resi9 R9R22225 residual current circuit breaker provides essential protection against earth leakage currents. This 1P+N device with a rated current of 25 A and a sensitivity of 30 mA instantly disconnects the circuit when a fault is detected, safeguarding people and equipment from electric shock and fire risks. Its Type A design ensures reliable operation even with pulsating DC residual currents, making it suitable for modern installations with electronic loads.

Why choose it

This RCCB combines proven Schneider Electric quality with precise protection. Its Type A tripping characteristic handles both AC and pulsating DC residual currents, a necessity for circuits with washing machines, induction hobs, or EV chargers. The compact 2-module width saves space in distribution boards, while the robust terminals and high mechanical endurance ensure long-term reliability.

Ideal use cases

• Residential distribution boards for socket and lighting circuits
• Commercial small offices and retail spaces
• Protection of circuits with electronic appliances and drives
• Upgrading existing installations to meet current safety standards

Good to know

The Resi9 series is designed for easy installation and compatibility with standard DIN rail enclosures. Always ensure the upstream overcurrent protection is coordinated with the RCCB's rated conditional short-circuit current. For maximum safety, test the device regularly using the integrated test button.
