FirstLine® Wraparound Maintenance Bypass Switch

The new FirstLine® wall mounted Maintenance Bypass Switch (MBS) from Staco Energy Products Company features “make-before-break” interlock technology. Tailored to meet the needs of most UPS installations, this MBS provides a safe means of removing a UPS from the circuit while maintaining the connection between the load and the utility and not dropping critical loads. This proven interlock ensures that the switch is closed or opened in the proper sequence to avoid improper application of power to the system or to the load. With models available for 208Vac or 480Vac applications, the FirstLine® MBS is an ideal alternative to a complete power distribution system. “We designed the MBS to meet the needs of UPS users who demand safety but do not want a complete power distribution system” says Dave Kendall, Staco Vice President of Sales & Marketing. “Our make-before-break interlock ensures that the switches are opened or closed in the proper sequence, making the product effective and easy to use.”
