ELECTRICAL PROTECTION RELAYS - REQUIREMENTS FOR THE PRINCIPAL FAMILIES OF PROTECTION RELAYS - SPECIFICATION FOR THERMAL ELECTRICAL RELAYS
31-05-1991
23-11-2012
Sets out the performance conditions for dependent specific time measuring relays which guard equipment against electrical thermal damage by recording the flow of current in the relevant equipment. Also gives the parameters whose values have to be stated by the relevant manufacturers. Does not cover devices which are in compliance with BS 4941 and BS 5424.
