Description

The HE30 Series is a two-stage, hybrid surge suppressor designed for use on data or communication circuits where surges of 10KA (8 x 20us) or less are anticipated. This device will provide continuous and reliable protection for all of your sensitive electronics.

The #10 stud is used for mounting HE30 and serves as the grounding mechanism to ensure proper grounding of the internal protection scheme. Care should be taken to provide a clean, conductive surface that is bonded to earth ground and mounted as close as possible to the lines to be protected.

The HE30A is a polarized unit designed to be used on low voltage DC signal lines.  This unit has a black and black/red color-coded input pair, with a white and white/red output pair.

The HE30C is a non-polarized unit designed for use on low voltage DC signal lines.  This unit has a black and black/red color-coded input pair, with a white and white/red output pair.

The standard HE30 second stage clamp is from each line to ground (A) except in cases where the ground potential may vary. In this case, a line-to-line second stage clamp would be preferred.
