Interpretation: For the same design and construction of a terminal, within an homogenous series of circuit-breakers, the terminals are fitted with copper conductors of the smallest and largest cross-sectional areas, as specified in Table according to the minimum and the maximum rated current of the range, solid or stranded, whichever is the most unfavourable Each conductor is then subjected to a pull of the value, in newtons, shown in Table 11, according to the relevant Cross-section of the tested conductor When it is necessary, the tested values, for the different cross-sections with the relevant pulling force, shall be clearly indicated in the test report 142 142 © The British Standards Institution © BSI 2012 2008 BSEN EN60898-1:2003+A13:2012 60898-1:2003+A1:2004 BS EXAMPLE 1: For a product of rated current equal to 63 A, the range of nominal cross-sections to be clamped is 10 mm to 25 mm according to Table According to Table 11, the test shall be performed with a cable of 10 mm cross-section and a pulling force of 80 N followed by another test with a cable of 25 mm cross-section and a pulling force of 100 N EXAMPLE 2: For a product with a range of 10 to 63 A, the range of nominal cross-sections to be clamped is mm to 25 mm According to Table 11, the test shall be performed with a cable of mm cross-section and a pulling force of 50 N followed by another test with a cable of 25 mm cross-section and a pulling force of 100 N _ August 2007 © BSI The 2008 British Standards Institution 2012 © 143 143 EN 60898-1/IS2 Interpretation Sheet EN 60898-1:2003 English version _ Foreword This Interpretation Sheet to the European Standard EN 60898-1:2003 was prepared by the Interpretation Panel of the Technical Committee CENELEC TC 23E, Circuit breakers and similar devices for household and similar applications The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC on 2007-05-07 Subclause 9.9, first five paragraphs The circuit-breaker is subjected to 28 cycles, each cycle comprising 21 h with a current equal to the rated current at an open circuit voltage of at least 30 V, and h without current under the test conditions of 9.2 1) The circuit-breaker is in the closed position, the current being established and interrupted by an auxiliary switch During this test the circuit-breaker shall not trip During the last period of current flow the temperature-rise of the terminals shall be measured This temperature-rise shall not exceed the value measured during the temperature-rise test (see 9.8) by more than 15 K Immediately after this measurement of the temperature-rise, the current is steadily increased within s to the conventional tripping current Question: Is it correct to perform the whole test at ambient temperature and to verify at the end of the test the tripping of the MCB at the conventional tripping current, which is referred to 30 °C ? Interpretation: Yes, the whole test shall be performed at ambient temperature Tripping tests being performed according to the conditions of 8.6.1 and 9.10 _ August 2007 1) For information, the st paragraph of 9.2 reads as follows: The circuit-breaker is mounted individually, vertically and in free air at an ambient temperature between 20 °C and 25 °C, unless otherwise specified, and is protected against undue external heating or cooling 144 144 © The British Standards Institution © BSI2012 2008 EN 60898-1/IS3 Interpretation Sheet EN 60898-1:2003 English version _ Foreword This Interpretation Sheet to the European Standard EN 60898-1:2003 was prepared by the Interpretation Panel of the Technical Committee CENELEC TC 23E, Circuit breakers and similar devices for household and similar applications The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC on 2007-05-07 Subclause 9.10.2.1 For the upper values of the test current, the test is made at rated voltage Un (phase to neutral) with a power factor between 0,95 and The sequence of operation is O-t-CO-t-CO-t-CO The interval t being as defined in 9.12.11.1 The tripping time of the O operation is measured After each operation the indicating means shall show the open position of the contacts Question: In 9.10, there is a reference to the requirements of 8.6.1, where according to Table (Time-current operating characteristics), the test shall be performed without previous loading, at the reference calibration temperature (30 °C) Is it allowed to perform the test at ambient temperature?
