Defines the test procedures for enclosed low-voltage ac power circuit breakers as follows: a) Stationary or drawout circuit breakers of two-or three- or four-pole construction, with one or more rated maximum voltages of 635 V (600 for units incorporating fuses), 508 V, and 254 V for application on systems having nominal voltages of 600, 480, and 240 V; b) Unfused or fused type circuit breakers; c) Manually operated or power-operated circuit breakers with or without electromechanical or solid-state trip devices; d) Fused drawouts consisting of current-limiting fuses in a drawout assembly intended to be connected in series with a low-voltage ac power circuit breaker to form a non-integrally fused circuit breaker.
