Tmax design mould case circuit breaker ( MCCB ) Function: As one of the EBSEE most important products, EBS7M 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 installation. It is characterised by high quality, reliability and performance under all conditions, simplicity of installation and safety of operation. Innovation, technology and quality have always been the principles of guiding the development of EBS7M. The continual and constant evolution of the EBS7M has LED to further extending the range of the products. EBS7M has variety applications possbilities both in industrial and civil sectors. It can be used for motor protection, switch-disconnecting, 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 This means wider application possbilities 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 in generators and for the end users. Their performances are however of particular interest where critical situations arise or where complexs plant engineering solutions are needed. They also guarantee total selectivity of the protections up to full breaking capacity fo the circuit breaker installed on the load side. Main Technical Parameters 1)complete current range Frame type: A: 12.5~125A B: 32~160A C: 125~250A D: 250~400A E: 500~630A F: 400~800A G: 800~1250A H: 1600A 2) High-breaking capacity Rated breaking capacity: B(20kA), C(35kA), S(50kA), H(65kA), G(85kA), X(100kA) 3) Rated frequancy: 50/60Hz 4) Pole: 3P, 4P Normal working enviroment: 1) Ambient air temperature: -5C~+40c 2) resistance to salt spray and oil spray 3) ambitent environment free from explosive danger, air or conductive dust which may cause corrosionof metal 4) altitude: <2000m We can also offer many other different design such as NF, NS, S and so on series MCCB.
