19、00. The contact pins specified by the technical specification shall be wired according to EN 3841-100, Table 1 and installed in an insert. The signal contact shall be loaded with the lowest current and voltage indicated in the technical specification. Cables shall be arranged in such a way that a be

20、nding load may be applied by means of a weight or a suitable spring scale. 3.2 Procedure 3.2.1 Method Each contact pin shall be submitted to 20 inserting and extracting operations each with the tool specified in the technical specification and in accordance with EN 3841-509. 3.2.2 Contact retention

21、force Afterwards each contact pin shall be submitted to an axial preload as specified in the technical specification in order to take up contact slack in its cavity. The force specified by the technical specification shall then be applied for 10 s. The rate of increase of the force shall not exceed

22、5 N/s. The contact maximum axial displacement shall be measured in accordance with the technical specification while the force is applied and/or after the force is removed. 3.2.3 Radial load The bending load shall be applied (when possible) in the four main directions related to the housing of the c

23、ircuit breaker radially to the operating direction. The force specified in the technical specification shall be maintained for 1 min in each direction. One terminal shall be tested on each sample.
