Schneider Electric R9D01616 - interruttore differenziale magnetotermico Resi9 1P+N 16A curva B 30mA Tipo A 6kA

The Schneider Electric Resi9 R9D01616 is a residual current circuit breaker with overcurrent protection (RCBO) that combines short-circuit, overload, and residual current protection in a single compact module. Its Type A 30 mA residual current detection safeguards against both AC and pulsating DC earth leakage, while the B-curve magnetic trip handles moderate inrush loads reliably. With a 6 kA breaking capacity and a 16 A rated current, it is engineered for residential and light commercial distribution boards where space and safety are paramount.

Advantages

This 1P+N RCBO occupies just two 9 mm pitches on a DIN rail, freeing up valuable panel space without compromising protection. The screw terminals accept flexible conductors up to 25 mm² and rigid conductors up to 35 mm², ensuring secure, low-resistance connections. Its IP20 rating (IP40 when installed in an enclosure) provides finger-safe operation, and the device is tested to IEC/EN 61009-1 for consistent performance. The Resi9 series is known for its reliable tripping mechanism and long electrical endurance of 10,000 cycles, reducing maintenance and replacement costs.

Suitable for

• Residential distribution boards protecting socket outlets, lighting circuits, and appliances.
• Light commercial installations such as small offices, retail spaces, and workshops.
• Circuits requiring combined residual current and overcurrent protection in a single module.
• Applications with moderate inrush currents, such as LED lighting drivers and small motors.
• Retrofit projects where space is limited and a compact RCBO is needed.

Recommendations

For optimal protection, install the R9D01616 at the origin of each final circuit in residential or light commercial panels. Pair it with Schneider Electric Resi9 distribution boards and accessories to ensure full compatibility and compliance. Always verify that the circuit's maximum demand does not exceed 16 A and that the earth leakage current is below 15 mA to avoid nuisance tripping. A qualified electrician should perform installation and testing according to local regulations.
