Aerospace series. Requirements and test procedures for relays and contactors - Insulation resistanceWhat is BS EN 2349 302 Insulation resistance test of relays and contactors about? Relays and contactors are electromechanical switches that help in operating contact terminals and are used to channel the power from one electrical device to another. The purpose of BS EN 2349 302 is to test the insulation resistance of relays and contractors which eliminates the risk of rupture in case of extreme arcing in the equipment. BS EN 2349 302 is a European
