Switchgear Rating 1ph Make (kA)
The short-circuit current that the breakers are capable of "making" i.e. closing onto an existing fault.

Switchgear rating refers to capability of circuit breakers only. Substations are limited to the Fault Level Design Limits as outlined in Substation Fault Levels sections 2.4.3 of the LTDS main document.
