• All Ohio Brass Arresters are fully compliant with ANSI/IEEE C62.11 Standard
• (1) Maximum discharge voltage for a 10-kA impulse current wave which produces a voltage wave cresting in 0.5 μs. This can be used for coordination where front-of-wave sparkover was formerly used.
• (2) Based on a 500A surge of 45-μs time to crest.

• (1) Center line to center line is equivalent to phase-to-phase; center line to ground is equivalent to phase-to-ground. These are recommended minimum clearances only and as such are not intended to take precedence over existing construction codes or specifications.
• For appropriate packed weight, add 0.5 lb. per arrester.
