What do you mean by "the Switchgear"? Do you mean the 'switchgear assembly' (i.e. the switchboard or panel or distribution board,etc.) or do you mean 'the installed circuit breaker'?
A rating of 50kA @ 1s is generally a rating that could be either.
In most contexts I would take it to be the short circuit rating of the assembly (i.e. the busbar rating) but if there is the slightest doubt I would suggest asking the supplier/manufacturer for confirmation.
