In the 1991 edition the voltage limit specified in Table 20.1, Note 6, was 380 V maximum whereas th
21、e 1995 edition allows up to 400 V. As many of the Part 2s in the EN 60730 series still refer to the 1991 edition of EN 60730-1, for these Part 2s, Note 6 of Table 20.1 of EN 60730-1:1995, allowing up to 400 V, is used as an interpretation. 03/01/12/16 EN 60730-1:1995 Automatic electrical controls fo

30、he plug can be connected to a socket outlet rated for a higher load current than the control, the control shall be provided with an incorporated fuse or a protective device to limit the current to the controls rating. The testing of the protective function is done in the sequence of tests according
31、to 27.5. The plug and socket outlet part of the control shall comply with the appropriate standard for the plug and socket system. The control part shall comply with this standard. Clause 27 Add: 27.5 See annex H. Annex H Add: H27.5 The following overload tests are carried out on in-line cord contro
32、ls as indicated in 11.10.2 and provided with a plug and socket outlet: - Controls as specified without protective devices and without incorporated fuses are loaded for 1 h with the conventional tripping current for the fuse which in the installation will protect the control. - Controls protected by
33、protective devices (including fuses) are loaded in such a way that the current through the control is 0,95 times the current with which the protective device releases after 1 h. The temperature rise is measured after a steady state has been reached or after 4 h, whichever is the shorter time. - Cont
34、rols protected by incorporated fuses complying with EN 60127 shall have those fuses replaced by links of negligible impedance and shall be loaded in such a manner that the current through the links shall be 2,1 times the rated current of the fuse. The temperature rise is measured after the electroni
35、c switch has been loaded for 30 mm. - Controls protected both by incorporated fuses and by protective devices are loaded either as described above with incorporated fuses or with another protective device, choosing the test requiring the lower load. - Controls protected by protective devices which w
36、ill short-circuit only in case of overload shall be tested both as controls with protective devices and as controls without protective devices. The temperatures measured shall not surpass those indicated in table 14. CLC/TR 50455:2008 6 08/01/19/11.1 EN 60730-1:2000 Automatic electrical controls for
