IEC 62271-111-2005

This Standard applies to all overhead, pad mounted, dry vault and submersible single or multi-pole alternating current automatic circuit reclosers and fault interrupters for rated maximum voltages above 1000 V and up to 38 kV. The following is also included in section 1: In order to simplify this standard where possible, the term recloser/FI (reclosers/FIs) has been substituted for automatic circuit recloser or fault interrupter or both. NOTE--When reclosers are applied in substation, special considerations may apply.

The purpose of this project is to revise existing standard including, but not limited to: a) general update to bring the standard in line with current technology; b) update information on BIL, altitude correction, temperature rise; c) add information on other interrupting/insulating media (e.g. SF6); d) add transient recovery voltage requirements; e) add voltage ratings common to systems outside of North America

Revision Standard - Superseded. This Standard applies to all overhead, pad mounted, dry vault and submersible single or multi-pole alternating current automatic circuit reclosers and fault interrupters for rated maximum voltages above 1000 V and up to 38 kV.
