Maintenance Bypass Switch. Wrap around, push button, wall mount 20k 3-1.

PowerShield offers MBS (Maintenance Bypass Switch) solutions for all types of UPS applications. A correctly designed MBS enables a technician to perform maintenance on a UPS at any time, without interruption to normal business operations with no need to shut down your critical electrical load. While in the “Bypass” position the UPS will still receive power from the mains (or alternative power source) so that the technician can perform maintenance procedures, without interruption to the load.
