1. MCB Construction Basic-Essential for Best Engineering Colleges in MP
Students
Do you have the aim of exploring your career as an Electrical Engineer? Do you want
to deliver your valuable services in NTPC, BHEL or in other public sector companies?
If yes, it is essential for you to study about important yet fundamental electrical
components found nearby your home or college since the beginning of your career in
best engineering colleges in MP. Particularly, an electrical engineering aspirant
should compulsorily possess knowledge about MCB construction and its operating
mechanism, as mentioned in this blog post.
MCB is the acronym of Miniature Circuit Breaker that includes simple, free
maintenance and robust type of construction. This type of circuit does not require
any repairing or maintenance job; instead, one has to replace it with the new one at
the time of damage. MCB primarily possesses three major constructional parts, like
MCB Frame
Students studying B.E. from best engineering colleges in MP will be able to
know that frame of MCB incorporate suitable molded case. This type of frame is
strong, rigid and is available in the form of insulated housing to allow mounting of
various other related components.
Trip Unit of the Breaker
Trip Unit present in the Miniature Circuit Breaker acts as its main part, as assures
proper operation of MCB. Because of the presence of trip unit, the device possesses
two different types of mechanisms. Firstly, the device has bimetal mechanism that
provides protection from overload current condition and secondly, electromagnet
assures about protection against short circuit current conditions.
MCB Operating Mechanism
Faculties of best engineering colleges in M.P. further said that the operating
mechanism of MCB provides it with the proper means of manually closing and
opening operation of MCB. MCB has three different positions as OFF, ON and
TRIPPED. One can choose to latch the external switch in TRIPPED position, in case
the circuit breaker tripped itself because of over current condition.
On the other side, latch switch becomes on or off depending on the position of
switch. Therefore, by simply observing various positions of switching latch, you can
easily determine exact condition of MCB, whether it remains in switched off, tripped
or in closed position.
