Electrical tests for terminal blocks | Phoenix Contact
The deciding factor for measuring the minimum clearance is the rated surge voltage, the overvoltage category of the terminal block, and the expected pollution degree.
Terminal Block Voltage Rating Explained (With Examples)
A terminal block voltage rating is the maximum voltage the device can continuously withstand without insulation breakdown, tracking, or electrical arcing between
