This International Standard applies to connectors with rated voltages above 50 V and up to 1 O00 V and rated currents up to 125 A per contact@ for which either no detail specification (DS) exists or the DS calls up this standard for safety aspects.For connectors with rated voltages up to 50 V@ this standard may be used as a guide. In this case@ reference is made to IEC 60664-1 for clearances and creepage distances.This standard does not apply to connectors in or on equipment where the applicable safety standard for the equipment includes comprehensive safety requirements for those connectors.
