Beskrivelse

This document applies to residual current monitors having rated voltages not
exceeding 440 V AC and rated currents not exceeding 125 A for household and similar purposes.

RCMs are intended to monitor the residual current of the installation and to give a
warning if the residual current between a live part and an exposed conductive part or
earth exceeds a predetermined level.

RCMs covered by this standard are not intended to be used as protective devices.

RCMs detect residual currents that may circulate in an AC circuit (e.g. residual
alternating current, residual pulsating direct current, residual smooth direct current),
whether suddenly applied or slowly rising.

NOTE 1 – RCM for DC systems are under consideration.

This document applies to monitors performing simultaneously the functions of detection of
the residual current, of comparison of the value of this current with the residual operating
current of the device and providing the prescribed warning signal(s) when the residual
current exceeds this value.

RCMs having internal batteries are not covered by this document.

The requirements of this document apply for normal environmental conditions (see 7.1).
Additional requirements may be necessary for RCMs used in locations having
severe environmental conditions.

This document does not cover Insulation Monitoring Devices (IMDs) which are covered by
the scope of IEC 61557-8.
