In case a circuit breaker is tripped by OCR which operates against the faulty current (Over Current Relay),
Trip Alarm switch provides the information regarding the trip of circuit breaker by sending the electrical signal from
the mechanical indicator on main cover of main circuit breaker or internal auxiliary switch.
When a circuit breaker tripped by faulty current, a mechanical trip indicator (MRB, Manual Reset Button) pops out
from the main cover and the switch (AL) which sends control signal electrically is conducted to output the
information occurred from faulty circuit breaker.

To re-close a circuit breaker after a trip, press MRB to reset it for closing.
