Overview

American Innovations’ High Energy Surge Arrester reliably handles stresses found in field environments – effectively protecting rectifiers and Bullhorn remote monitoring units (RMU’s). The High Energy Surge Arrester provides superior protection of electrical equipment. It is specifically designed for easy installation internally or externally to the rectifier. The High Energy Surge Arrester passes all design tests for arresters per IEEE Std C62.11TM-1993.

Key Benefits

  • Designed with a full 40 kA surge capability - Four times the level of traditional secondary surge arresters
  • Incorporates Metal Oxide Varistors (MOV) - Superior energy handling assures long service life even in the most severe conditions
  • Fully enclosed stainless steel housing - Easy to install internally or externally

1 - Tests were performed in accordance with applicable sections of IEEE Std C62.11™ - 1993 standard (Metal Oxide Surge Arresters for Alternating Current Power Circuits).

2 - Based on a current impulse, which results in a discharge voltage cresting in 0.5 µs.
