The combination of tripping curves of the electro-magnetic release and the thermal bi-metal release result in an overall tripping curve for overload protection. IEC 60255-1:2009 specifies common rules and requirements applicable to measuring relays and protection equipment including any combination of devices to form schemes for power system protection such as control, monitoring and process interface equipment in order to obtain uniformity of requirements and tests.
