BAM8 series moulded case circuit breaker (hereinafter referred to as breaker) is a new type breaker developed by our
company with international advanced technology. It ’ s rated insulation voltage up to 800V. The breaker is mainly used in
distribution netwo rk of AC 50Hz/60Hz, rated voltage up to 690V,rated operating current up to 1250A to distribute electric
power and to protect the line and the equipment from being damaged due to overload, short circuit and under-voltage .It can
also be used for infrequent motor start and for motor overload., short circuit and under-voltage protections.
The circuit breaker, according to its different rated limit short-circuit breaking capacity , is divided into three kinds: S type
(standard type), H type (higher type), R type (limit current type).
The product features small volume, high breaking capacity and short arcing distance so that it is an ideal product for users.
�
The product is in conformity with the standard IEC60947-2.

5.1.2 Under-voltage release
The under – voltage release shall act to switch off the breaker when the power voltage decreases (even if slowly decreases )
to 70% -35% rated voltage .It shall prevent the breaker from reclosing, if the power voltage decreases to less than 35% rated
volta ge .It shall ensure to close the breaker ,if the power voltage is equal to or greater than 85% rated voltage.
The rated voltage of the under-voltage release is 50Hz, 230V and 400V.

7.1 Connecting wire
A
single-core copper wire with PVC insulation is used as connecting wire for the breaker. The wire section is selected
according to table 13.
Table 13
7.2 Installation
7.2.1 Before you install a circuit breaker, you must fist check up contents in boxing paper, then fix the breaker vertically on an
installing board by bolts.
7.2.2 Wiring in a main circuit
�Wiring of the fixed connection
:
An end of wire, with PVC and its section specified in item 7.1, after insulation outer PVC
in suitable length is stripped, is inserted into the hole of a hoop. The outer of the hoop must tightly be pressed, and the
wire must be fastened, then the junction hole of the hoop is tightly connected with the terminal of breaker by screws. If
it
is copper row, the connecting board must fist be fixed on the breaker, then the copper row is fastened with the
connecting board.
�Wiring of the rear connection
:
The connecting board is first fixed according to fig.16, then
it
is fastened with an
appropriate wire.
7.2.3 Auxiliary circuit wiring
An auxiliary circuit is connected according to a corresponding breaker board.
7.2.4 Insert the phase separator between phases.

7.3 Use and maintenance
7.3.1 In the choice of breakers, their technical parameters must correspond to objective requirements of practice.
7.3.2 Various characteristics and accessories of the breakers are regulated by the special technician, so you can not adjust
them by yourself.
7.3.3 After overload and short circuit protection of the breaker, the breakdown must first be fixed, next, the breaker is switched
on and operated.
7.3.4 Periodically checking and keeping clean and reliable insulation.
