It shall be used together with EN 2349-100. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated re

17、ferences, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

18、Requirements and test procedures for relays and contactors Part 303: Dielectric strength 3 Mounting method The switching device shall be wired in accordance with EN 2349-100. The rated overload current and the open circuit voltage shall be applied in accordance with product standard. The test sample

19、 shall be mounted in still air. 4 Test procedures 4.1 Each operating and resting contact shall be able to connect, conduct and disconnect the overload in accordance with the product standard. The operating and normally closed contacts shall be tested separately. 4.2 The coil of the switching device

20、shall be energized with the rated voltage during the test. The contacts shall be monitored during connection, conduction and disconnection. A functional defect of the test sample shall constitute a failure. A voltage drop across closed contacts over 10 % of the supply voltage shall constitute a fail

21、ure. During the test, the housing of the relay or contactor shall be connected to the d.c. earth or neutral wire of the electrical installation by a fuse with a rating of 5 % of the rated resistive contact current, but not greater than 3 A. 4.3 Blowing of the fuse shall constitute a failure. 4.4 Tes

22、t cycle: connection time: (0,2 0,05) s for a.c.; (0,5 0,05) s for d.c. disconnection time: (20 1) s. Number of switching cycles: see product standard.1) In preparation at the date of publication of this standard.
