the short circuit breaker is installed to prevent electric shock to
the human body, fire caused by short circuit, and damage
to the electrical equipment by arc at voltages below 600 volts.
The circuit breaker tester is an instrument that checks the rated
sensitivity current (current that the circuit breaker detects
as short circuit) - trip time value.
The value of leakage current can be adjusted arbitrarily.
The time from the time of the short circuit to the time of
operation of the short circuit breaker can be measured.
