19、nts and test procedures for relays and contactors Part 301: Pick-up and drop-out voltage 3 Method 3.1 Mounting The relay or contactor shall be wired in accordance with EN 2349-100 and the rated contact load. 3.2 Test procedures Each normally closed and normally open contact shall be loaded with 25 %
20、 of the resistive load as specified in the product standard. The open contact voltage shall conform to the value specified in the product standard. During this test the coil of the relay or contactor shall be energized at the rated voltage. The contacts shall be monitored for opening and closing in
21、the sequence specified. Test cycle: connection time: (1,5 1) s; disconnection time: (1,5 1) s. Number of cycles: see product standard. 1) In preparation at the date of publication of this standard.
