Bypass/Isolation Switches

Manual Bypass/Isolation Capability Allows Emergency ATS Bypass, Maintenance and Testing

Russelectric bypass/isolation switches provide all the functions of a Russelectric automatic transfer switch plus the ability to bypass power from a live source to load in the event the transfer switch is disabled. It also allows the transfer switch to be isolated and de-energized for maintenance, testing, or repair.

  • True drawout construction allows safe, easy removal of the transfer switch and eliminates the need to make any electrical or mechanical disconnections.
  • Russelectric is the only manufacturer that offers both load-break and no-load-break bypass switch designs.

Bypass/Isolation Switches are available in the following versions:

Compartmentalized Design Simplifies Installation, Ensures Personnel Safety

Russelectric bypass/isolation switches are designed with 3 distinct compartments, separated by barriers, to simplify switch installation and protect personnel.

Bypass Switch Compartment

This compartment contains the bypass/isolation switch assembly including operating handle, mechanism and controls. It also houses associated buswork and the ancillary wiring (which must always remain energized). No access to this compartment is necessary during normal operation including bypass and isolation of the transfer switch. As a result, it significantly increases operator safety.

Automatic Transfer Switch Compartment

This compartment contains the ATS assembly and its ancillary circuits. Once the ATS has been isolated, the door can be opened and the switch safely drawn out.

Power Connections/Bus Compartment

This separate rear compartment contains all power connections for the bypass/isolation switch. Designed to simplify power terminations, it protects switch components and equipment from damage during the pulling of feeder cables or the installation of feeder bus. Bottom, top and even side feeder connections are available. All RTS Series bypass/isolation switches are designed with rear access — either a removable rear panel or a hinged/latched 3-point rear door.

Self-Connecting Secondary Controls | B

Self-connecting transfer switch has secondary control contacts which eliminate the need to make manual connections or disconnections.

Bypass Switch Contacts Are Identical in Design to ATS Switching Contacts | C

Rugged bypass switching contacts are identical in design and carry the same ratings as the ATS switching contacts.
