Schneider Electric R9R22240 aardlekschakelaar 1P+N 40A 30mA

Electrical faults can occur without warning, putting people and property at risk. The Schneider Electric R9R22240 residual current circuit breaker (RCCB) from the Resi9 series is engineered to detect earth leakage currents of 30 mA and disconnect the circuit instantly, preventing electric shock and fire hazards. This 1P+N device with a rated current of 40 A is ideal for residential and commercial installations where reliable protection is non-negotiable.

Who is it for

This RCCB is intended for electricians, panel builders, and homeowners who need a dependable earth-leakage protection solution for single-phase AC networks. It is suitable for use in distribution boards, consumer units, and modular enclosures, providing essential protection for circuits supplying sockets, lighting, and appliances.

Main features

• Type A earth-leakage protection: detects alternating and pulsating DC residual currents, suitable for circuits with electronic loads.
• Instantaneous tripping: responds immediately to leakage faults, minimizing risk.
• 1P+N configuration with neutral on left: simplifies wiring and saves space in the enclosure.
• Rated current 40 A: handles high-load circuits while maintaining protection.
• 30 mA sensitivity: provides personal protection against electric shock.
• Compact 2-module width (4 pitches of 9 mm): fits standard DIN rail distribution boards.
• Robust tunnel terminals: accept rigid conductors up to 35 mm² and flexible up to 25 mm², with a tightening torque of 3.5 N·m.
• Complies with EN/IEC 61008-1: meets international safety standards.

Tips

For optimal protection, pair this RCCB with a suitable miniature circuit breaker (MCB) upstream to handle overcurrent and short-circuit conditions. Ensure the upstream MCB rating does not exceed 40 A to maintain the 6 kA conditional short-circuit rating. Always test the RCCB regularly using the test button to verify proper operation.
