IEEE C37.30.3-2018

This document provides standard requirements for interrupter switches, interrupters, or interrupting aids used on or attached to switches rated for high-voltage ac above 1000 V and used indoors, outdoors, or in enclosures for non-fault current interrupting for which an interrupting duty is assigned. This standard covers preferred ratings, construction, application, loading, installation, operation, and maintenance guidelines. This standard does not apply to load-break separable insulated connectors, circuit breakers, circuit switchers, metal-enclosed switchgear, pad-mounted switchgear, reclosers, sectionalizers or other switching devices that are covered by other IEEE standards.
