AR2-E2 (DISCONTINUED)

There is no load current rating. With this model no load current flows because it is connected in parallel to the load.

The “AR-PS” is available. Note that this is not JIS-compliant.

Yes, you need it regardless of the presence or absence of voltage. We recommend the AR-LP.

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...

Yes. It's the E9731TW. (Please consult with your dealer at the time of purchase.)

Yes. The adapter for mounting on a DIN rail is an option.

They are voltage limiting lightning arresters.

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) .

Yes, that is not a problem.

Yes, the AR-SA.

Yes, the AR-LP. It has a rated (load) current of 2 A. Note that this does not support JIS.

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. ...

Yes.

You can use the AR-LP. Note that this is not JIS-compliant.

It uses a zinc oxide varistor.

Yes, the AR-LP (for 2-wire pulse signals, 50 VDC or less)
