Poznámky redaktora
This also the case for connectors rated for currents exceeding 125 With regard clearance distances and creepage distances, DIN 124-1 (VDE 0115) used.000 and currents most least for equipment using common industrial connector sizes. For this reason, some the conditions are redefined.188 5. 5. primary circuits equipment - Indoor power supply circuits . For long time, connectors were limited voltages more than 1.2.1 Clearance and Creepage Distances As explained above, the regulations for railway technology {VDE 0115) are used when designing connectors not specified VDE 0627. This was due the low demand for such products, well technical reasons. Modular design increasingly common railway vehicle manufacturing.1. 5.000 VAC 1,500 VDC.c.1 Overvoltage categories acc. Recently, the demand for high-power connectors has increased, especially railway engineering and power generation. result, there more demand for removable interfaces.2. DIN 50124-3 (VDE 0115, Part 107) O Circuits that are protected against external and internal overvoltages and which only very low overvoltages occur because - they are not directly connected the contact line, - they are operated indoor, - they are within equipment device Examples: - Data lines - Circuits not connected power distribution system - Screened circuits - Circuits being operated indoor OV same but with higher requirements Definition - Circuits with usual transient overvoltages - Circuits with normal availability requirements Examples: - 230 a.2 Connectors for high Currents and high Voltages VDE 0627 longer applies connectors designed for voltages above 1
