Current limitation
ABB's utilization of current limiting circuit breakers
brings a whole new level of protection and peace of
mind to the distribution of electrical power on the
data center floor. Two of the most notable benefits
of current limitation are increased protection for
downstream system components and the
mitigation of arc flash hazard for workers. Both
mechanical and thermal forces are drastically
reduced through current limitation, which in a data
center, means less potential damage or strain on
the sensitive and expensive IT equipment. This
heightened protection helps remove worries of
extended downtime due to repairs or replacing of
damaged equipment. Current limitation is also the
driving factor to reducing the energy released
during an arc flash event.
