MNS® Rear

Rear access low-voltage switchgear assembly

Where switch room space limitation or operation accessibility demands separation of operation and cable termination area, the MNS Rear solution provides the perfect fit. The possibility to access cable termination at the rear side combined with options to stack multiple ACB in a single section without any derating, the MNS Rear layout further significantly reduces the width of power distribution switchgear bundled with maximum safety and ease of operation and maintenance.

Main benefits

  • Unmatched safety for protection of personnel and plant
  • Reduced operational expenditure through maintenance free bus bar and frame design by MNS
  • Increased availability through modular design withdrawable technology
  • Reliable, flexible and scalable design
  • Space saving due to separation of cable termination accessible from the rear side
