why circuit breaker closing time is always higher then
tripping / opening time.

Answer Posted / thayathidavan gopalan

Closing time is always greater than opening time.Closing a
breaker means you have to close against the inertia and it
is closing on no load normally.
Opening time should be fast as possible to interrupt the arc
fast to avoid damaging of the contact , It depends upon
the manufacture and design of driving mechanism ,make to
open as fast as possible.

opening during fault shall be as fast as good to maintain
system stability also
