Can NSX switch disconnectors protect against short circuit?

The switch disconnector can make and break its rated current. For an overload or a short circuit, it must be protected by an upstream device, in compliance with installation standards.
The cirrcuit breaker/ switch-disconnector coordination tables determine the required upstream circuit breaker.
However, due to their high-set magneic release, Compact NSX100-630A switch disconnectors are self-protected.
