Schneider Resi9 RCD 2P 40A 30mA Type A R9R22240

Fault currents can cause serious damage to electrical installations and pose a risk of electric shock. The Schneider Resi9 RCD (Residual Current Device) type A, 2-pole, 40 A, 30 mA, provides essential protection by detecting residual currents and disconnecting the circuit quickly. This device is ideal for residential and commercial applications where protection against alternating and pulsating direct residual currents is required.

Who is it for

This RCD is designed for electricians, panel builders, and homeowners who need reliable protection for circuits with single-phase loads. It is suitable for use in distribution boards and consumer units, protecting against earth leakage currents that could cause electric shock or fire.
