Technical
Features :
To suit typical circuit and market requirements MCB's are manufactured
in two different categories.
B Type (L Series) : This series is specially suitable
for protection of equipment like Ovens, GLS lamps , Geysers and
general electrical lighting systems. The magnetic tripping of B
types MCB starts, above 4 times of the rated current.
C Type ( G Series ) : are designed to protect circuits
with inductive loads like motor and generator etc The magnetic tripping
commences above 5 times the rated current |

| MINIATURE CIRCUIT
BREAKERS (M.C.B) |
MCB, is an advanced technology Miniature Circuit Breaker,specialy designed
to control and protect all types Electrical installation as well as commercial
and industrial appliances. BENTEX-Linger MCB safeguard the installations
against damage resulting short circuit fault and circuit overloads and
also serves unique dual purpose of both a switch as well as fuse.BENTEX-Linger
MCB's are conforming to IS 8828-96. There are available in SP,DP,TP,TPN
& FP. |
| FEATURES : |
MCB's are compact in size ,covering entire range of B Type (L Series),
C Type (G Series) and "DC" Series, from 0.5 to 100 Amps and
isolators upto 63 Amps. Bentex-Linger MCB's are using internationally
accepted design and technology.
MCB's Life expectancy are tested for 1,0,000 mechanical operations and
25,000electrical operations thereby making the MCB a life service device
Current Limiting Features: Are available in single and multiple version
with or without neutral breaking. This guarantees universal application:
especially suitable for installations with a heavy short- circuit and
in load up to 10 KA. Under short- circuit conditions high values of
over current occur.Under these circumstances a plunger in the solenoid
moves with sufficient force to physically separate the contacts.
Thermal Release:Small overloads are detected by a finally calibrated
bimetal element.If the current is greater than the rated current of
MCB, the deflection bimetal will be sufficient to trip the MCB .
Magnetic Release:When a over current of between 3 to 5 times rated current
for B Type(L Series) and 5 to 10 times rated current of C types( G series)
MCB changes from thermal to magnetic. The MCB will trip in less than
100 m sec. This is the reason of instaneous tripping.
|
CONTACTS
: Contacts are made of pure silver.This
provides definite advantages of MCB
|
MCB, such as low contact resistance reduces voltage drop and reduction
in power loss. It helps to low heat generation: quick arc removal and
thereby long life.
|
MOUNTING ARRANGEMENT:
MCB's can be installed on Standard(35 mm)DIN Bars by a simple snap action.The
MCB mounting is easy tube snapped on and can be removed easily from
DIN Bar.
|
MECHANICAL
INTERLOCKING OF MULTIPLE MCB's : The tripping mechanism of all
multiple MCB's is connected internally. This ensures simultaneous tripping
of all poles even if the fault occurs in any one of the phases ,thus preventing
single phase. |
