Benefits of MVS10-12:

  1. Vacuum circuit breakers of this series can significantly reduce the dimensions of the switchgear
  2. The non-separable pole design increases dielectric strength, insulation reliability and protects cameras from adverse environmental influences.
  3. The design of the vacuum chamber of the circuit breaker eliminates increased wear of the contacts and their premature erosion thanks to AMF technology, which distributes the arc evenly over the entire surface of the contacts.
  4. The circuit breaker drive has high mechanical reliability and low power consumption
  5. The ability to install mechanical interlocks to lock other switchgear devices from the vacuum circuit breaker.
  6. The ability to install maximum current releases 3A or 5A for use in circuits with bypass.
