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.
