Specifies essential safety requirements for residual current devices for approval and test purposes. It is to be read in conjunction with AS/NZS 3100.

This Standard applies to residual current devices and residual current relays intended to isolate supply or initiate a ‘tripping’ signal to isolate supply to protected circuits, socket-outlets or equipment in the event of a current flow to earth, which exceeds a predetermined level, and —(a) have rated residual currents not exceeding 300 mA;(b) have rated load currents not exceeding 125 A a.c.; and(c) designed for use at low voltage.The devices may be fixed or portable or, may be integral with a switching device or miniature overcurrent circuit breaker or, may be supplied as a separate attachment.This Standard does not apply to—(i) devices intended to be used with a particular circuit breaker other than a miniature overcurrent circuit-breaker, as defined in AS 3111; or(ii) devices intended to protect an electricity authority distribution system; or(iii) devices covered by AS 2081 and for protection of equipment for mines.
