MCB, a compact designed device to cope with complexities of
electrical installations with high safety features to give
protection against electrical hazards in dual ways i.e:-
- Thermal Overload
- Magnetic short-circuit
GECO MCBs are available with
two type tripping characteristics for
different type of
Suitable for installations with a low and steady currents
domestic and non inductive loads.
Fit for use in installations with high in-rush current peaks and
require closer overload protection. These include inductive
such as motor, air-conditioners, halogen & sodium vapor
strengthen flame retardant PBT fibre glass housing.
inlaid copper contacts to ensure zero resistance and
arc-chute chamber for efficient arc quenching.
calibrated thermostatic bimetal for closely controlled
electro magnetic release system for short circuit
which clears the fault in a few milliseconds.
has recognised the growing importance of limiting power
switchgear devices and stipulated maximum permissible power
values per pole for MCBs. Geco MCBs have power loss figures
40-75% of the stipulated values which contribute -
to energy saving.
terminal screws are well recessed to avoid any unpleasant
accidents. The terminals are "Finger-Safe".
TRIPPING OF ALL PHASES IN MULTIPOLES

usage in locomotive and electric trains, mounting on
motors etc. GECO MCBs find maximum
As per the wiring regulations, it is

/ SEALING ARRANGEMENTS
This arrangement is possible in both ON
and OFF positions. This
eliminates the hazards of closing when
personnel are working on
circuits as well as the nuisance of
