Bowthorpe pioneered the development of polymeric housed surge arresters in the early 1980's and since 1986 have a proven service experience across the globe, operating in the worlds toughest environments.

Bowthorpe "OCP" silicone surge arresters have been designed and tested to meet our customers toughest environmental conditions and to meet the requirements of IEC60099-4. Our gapless zinc oxide polymeric arresters have been in service since 1994 and now the OCP ranges builds on this experience and know how.

OCP is the latest gapless, zinc oxide arrester family from Bowthorpe.

The OCP development was based on 25 years of internal experience in arrester design and manufacture within the Tyco Electronics Energy Division. The final "OCP" qualification was performed in independent laboratory facilities in Europe.

OCP cores are manufactured using superior ZnO varistors, which display excellent thermal and current handling characteristics due to the guaranteed homogeneity of the varistor volume.

This superior thermal behavior yields products with:

  Excellent TOV performance.
  Safe, non-shattering failure in the short circuit test by pre-failing to higher fault currents.
  High energy handling capability.
