AS 3190-1994

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

This Specification applies to residual current devices and residual current relays (of the current-operated type), with a rated residual current not exceeding 300 mA, designed for operation at low voltage, having a rated load current not exceeding 100 A a.c., and intended to isolate supply or initiate a tripping signal in the event of a current flow to earth in the protected circuit, in excess of a predetermined level.This Specification does not apply to residual current units whose design is dedicated for use with a (particular) circuit-breaker, other than a miniature overcurrent circuit-breaker as defined in Appendix A of AS 3111.NOTE: It is intended that residual current units associated with circuit-breakers rated in excess of 100 A, either integrally or as an added unit, be covered by a separate Standard.It is not intended that this Specification apply to residual current devices or other earth-leakage devices for the protection of supply authority distribution systems, or for protection of equipment in mines covered by AS 2081.
