The insulation resistance value at the surge arrester terminal block between the I/O terminals and ground is 100 MΩ or more/500 VDC. The withstand voltage between I/O terminals and ground is 1000 VAC/1 minute (or 1500/1 minute for the AR-PH onl...
For converters with an open detection function, during open detection the line-to-line is 40 V, therefore we recommend using the AR-HA (max. continuous line-to-line voltage of 70 V) .
A DIN rail adapter can be included with an option when purchasing the surge arrester. If you need to purchase an adapter later, select the AR8-01_DIN rail adapter.
