For cross sections from mm² In sectors after current-limiting ms) protection devices <=630 (Icp >10 kA) At unaffected short-circuit current the grid Icp >10 (in front the switchgear), forward current will flow of the period with upstream protection device.4 The required creepage distances are based 60664-1 and are identical with the values for the dimensioning terminal blocks according 60947-7-1(2, 3).g. 6 Installation equipment 10.2.32 0. to internal electrical effects Inserted components like terminal blocks are not affected.14 0.11.6 Installation and tight fit terminal blocks secured the requirements and relevant tests according the product standard.8 Secured selection the terminal block well its type test according 60947-7-1(2). measurement calculation.2.2 61439-1, the switchgear manufacturer does not have provide evidence this case. The switchgear manufacturer has provide evidence for the maximum forward current declaration the terminal block’s Ipk (surge current strength, which the terminal block able conduct without being destroyed). According the section 10. 10 Temperature rise limits 10.06 11 Short-circuit withstand strength 10. The calculation the terminal block‘s power dissipation can take place the application means of the electrical resistance function current: Ploss = Rmax * I2 Following maximum resistances per electrical potential according to EN 60947-7-1(2, subject the cross section for the terminal block are permitted: Cross section/mm² 1.9 Tests the insulation properties are part the dimensioning type tested terminal blocks • Operating frequency dielectric strength 10.08 0. • Surge voltage strength 10.3.2 • Corrosion resistance 10.2.5.Checklist design verification according IEC/EN 61439 Design verification for terminal blocks and their accessories Nr.1 • Resilience extreme heat and fire due 10.11 For cross sections mm² In sectors after current-limiting (5ms) protections devices <100 (fort Icp <10 kA) At unaffected short-circuit current the grid Icp <=10 (in front the switchgear), forward current with maximum will arise with upstream protection device. 8 Connections for conductors inserted from outside 10.7 Not relevant, has judged the end use for terminal blocks.83 1.33 1.3 Terminal blocks are designated for the installation cabinets, thus not relevant 3 Clearances 10.4 The required clearances are based 60664-1 and are identical with the values for the dimensioning terminal blocks according 60947-7-1(2, 3). integrity protective circuits The quality and consistency the conductor connection has verified resistance • Effective continuity between the exposed 10.2. 4 Creepage distances 10.42 0.2
