AR Series Surge Arresters

The high-performance AR surge arrester absorbs the potential of an inductive lightning surge caused by a lightning discharge to protect electronic instruments. The plug-in arrester consists of a separable main unit and terminal block.

  • Absorbs large surge voltages immediately.
  • Simple circuit configuration and excellent adaptability to a distributed control system.
  • Plug-in connection of the main unit with the terminal block, eliminating concerns about an open-circuit state even if the main unit is removed.
  • Support JIS

【Support Information】List of RoHS

This is a list of recorder and controller products that support the RoHS (2011/65/EU) directive.

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, the AR-LP (for 2-wire pulse signals, 50 VDC or less)
Can I mount on DIN rails?
(ns-faq-ar-16004-select)
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, the AR-SA.
Can I use the AR-RT for the Pt50 Ω RTD?
(ns-faq-ar-16005-select)
Yes.
It uses a zinc oxide varistor.
Yes, that is not a problem.
You can use the AR-LP. Note that this is not JIS-compliant.
Yes, the AR-LP. It has a rated (load) current of 2 A. Note that this does not support JIS.
There is no load current rating. With this model no load current flows because it is connected in parallel to the load.
