BRM6 Moulded Case Circuit Breaker
As one of the Britec most important products, BRM6 moulded case low-voltage circuit breakers offer good
performance that meets the full spectrum of application requirements, from small users to large industrial electricity
distribution installations. It is high quality, reliability, and performance under all conditions, simple for installation
and safety of operation.
Innovation, technology and quality have always been the principles of guiding the development of BRM6.The
continual and constant evolution of the BRM6 has led to further extending the range of products.
Special technical solutions, such as two fixed contacts for each arcing chamber, offers excellent performance in
terms of breaking, fault current limiting and specific let-through current capacity.
BRM6 has variety applications in industrial and civil sectors. It can be used for motor protection, switchdisconnecting,
circuit-breaking, and residual current circuit breaking, as well as specific ranges (for motor protection
and switch-disconnecting) complying with the standard of IEC60947-1, IEC60947-2, IEC60947-4-1.
This means wider application possibilities both in industrial and civil sectors. They can therefore be mounted in
primary Power Center and secondary Panel Board distribution switchboards, for motor protection and control
Motor Control Center, in generators and for end users. Their performances are, however, of particular interest where
critical situations arise (very high rated and fault currents), or where complex plant engineering solutions are needed
(special coordination requirements and plant automation). They also guarantee total selectivity of the protections up
to full breaking capacity of the circuit-breaker installed on the load side.
