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 network 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.
