AC type residual current devices

(145 Products)

AC type differential switches ideal for protecting people against indirect contact and for detecting alternating earth fault currents.

These devices are essential for the safety of residential and industrial electrical systems. Their rapid and reliable operation ensures power interruption in the event of a leak, helping to prevent fires and electrocutions.

Available in various nominal current and sensitivity sizes (e.g. 30 mA , 300 mA ), AC type differential switches can be easily installed on DIN rails and are compatible with modular electrical panels.

They are the most common choice in residential settings for protecting circuits with traditional loads, such as sockets and lighting.
