Surge protection for DC power supply

The OBO V20 and V50 DC surge arresters

New players in the strong OBO team against surge voltages: The V20 and V50 DC arresters guarantee reliable surge protection for DC power supplies. Their high-performance varistor technology guarantees a follow current interrupt rating of 25 kA. The arresters are ideally suited for use in the field of 5G expansion.

They have a very low voltage protection level and can be used up to lightning protection Class III. The arresters have a remote signalling contact and, with a width of just 1 part unit (18 mm), are real space-savers.

The variants at a glance:

  • Type 2 arrester for 48 V DC (60 V DC max. continuous operating voltage)
  • Type 1+2 arrester for 48 V DC (60 V DC max. continuous operating voltage)
  • Type 2 arrester with 20 kA IN
  • Type 1+2 arrester with 12.5 kA Iimp
