Frequently Asked Questions about RS 40A
The RS 40A is an industrial residual current switch that protects circuits by detecting leakage currents, monitoring load conditions and interrupting power in unsafe situations. It combines residual current detection with overload and short-circuit protection in one compact device, guarding against hazards such as electric shocks, short circuits and overloads in industrial, commercial and utility installations.
It is fitted in distribution boards, motor control centres, automation panels and residential or commercial electrical installations. The compact industrial form suits distribution boards, switchboards and control panels, and quick mounting and connection allow fast deployment. It is built for the conditions found in industrial and commercial electrical environments and integrates with PLC systems, automation panels and distribution setups.
Cost depends on the quantity ordered and how the switch fits into the wider distribution board or control panel being built, so no single figure applies. Send details of the circuits to be protected and where the device will be mounted, then request a written quotation so the switch is confirmed as suitable for the installation before ordering.
