Separate a complete switchgear assembly from a standalone outdoor circuit breaker. Specify system voltage, continuous and fault current, protection, control supply, service access and insulation medium. Medium-voltage panels, low-voltage boards and outdoor breakers are coordinated equipment, each with its own selection criteria.

Every breaker, switchboard, and control panel needs a short-circuit current rating at least equal to it, and non-dwelling service equipment must be field-marked with the value under NEC 110.24.

Here is how North American buyers match construction class, voltage, and fault duty to the application.

The right choice turns on footprint, environment, voltage class, and tightening SF6 rules.
