AR Surge Arrester

Brand: Yokogawa

Yokogawa Surge Arrester, AR Yokogawa Surge Arrester, AR
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.
Features
  • 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
    • JIS C 5381-21 (category: C1,C2):
      •  AR-SA, AR-HA, AR-TC, AR-RT, AR-HP, AR-LP, AR-SP
      • AR-SY, AR1-B2, AR1-D62
    • JIS C 5381-1 (class Ⅱ): 
      • AR-PS, AR-PH, AR-PW
