| Overvoltage category | Rated voltage (AC) | Uimp required | |----------------------|--------------------|----------------| | II (household) | 230/400 V | 2.5 kV | | III (industrial) | 230/400 V | 4.0 kV | | IV (service entry) | 230/400 V | 6.0 kV |

IEC 61180-1 outlines the specifications for generators used to produce test voltages. It sets limits on the characteristics of the voltage waveform to ensure the stress applied to the test object is consistent and measurable. iec 61180-1

: Evaluates insulation under steady-state direct current stress. | Overvoltage category | Rated voltage (AC) |

Always check your product standard (e.g., IEC 60730 for controls) – it will reference IEC 61180-1 for test procedures. iec 61180-1

The required impulse withstand voltage () depends on:
