Schneider Resi9 RCBO, 1P+N, 16 A, B-curve, 30 mA, Type A, 6 kA, 2 Modules

Electricians and panel builders rely on the Schneider Resi9 RCBO to safeguard residential and light commercial circuits. Combining overcurrent and earth-leakage protection in a single 2-module device, it saves space while ensuring compliance with modern wiring regulations. The B16 rating suits general socket outlets and lighting circuits, while the 30 mA sensitivity protects against electric shock and fire risks.

Why choose it

This RCBO delivers dependable protection with a compact footprint. The B-curve handles moderate inrush currents from lighting and small appliances, while Type A sensitivity detects both AC and pulsating DC residual currents. Its 6 kA breaking capacity meets the needs of most residential distribution boards, and the screw terminals accept a wide range of conductor sizes for flexible installation.

Ideal use cases

• Protecting socket outlet circuits in homes and apartments
• Lighting circuits in residential and small commercial buildings
• Retrofitting older installations to add earth-leakage protection
• New distribution board builds where space is limited

Good to know

The Resi9 range is designed for easy DIN rail mounting and clear visual indication of trip status. The 2-module width frees up space for additional devices. Always verify local wiring regulations for required protection types and ratings. The device is suitable for use in distribution boards with an IP40 enclosure rating.
