the event fault, the
breaker electrically closest the fault should trip first.

22 SIGNUM
3SB3 Selector Switch
30 Class 52
Selector Switch
Semiconductor type material, such silicon, with more resistance than a
conductor, but less than that insulator.
Primary Switch
Transformer
Switchboard or
Switchgear Sections
Selective Coordination Applying circuit breakers manner that minimizes the extent
of outage the event fault.31
Secondary Unit Substation coordinated design consisting one more transformers
mechanically and electrically linked switchgear or
switchboard assemblies with outgoing voltage rated below
1000 volts.
Selector Switch manual switch with multiple contact positions.This can
be accomplished properly sizing and adjusting all breakers. Semiconductors
can manufactured produce devices such diodes,
transistors, thyristors, etc.
. Circuit breakers are typically
installed branching arrangement
