- Positive mechanical interlocks ensure that bypass/isolation functions are accomplished without danger of a short circuit between power sources.
- The bypass switch quick-break, quick-make contacts and basic operating mechanisms are identical to those of the transfer switch and have full load-break capability with the same electrical ratings.
- Single or dual operator versions
Russelectric® Open-Transition 30-Cycle Rated Bypass/Isolation Switches are available in the following versions:
Safe Manual Operator
The bypass/isolation switch functions as a manually operated backup transfer switch when in the “Isolate” position. The bypass handle can be used to manually transfer the load to the selected source with the same speed as the automatic transfer switch. The preloaded switch mechanism transfers instantaneously, precluding heavy arcing or the possibility of flashover.
External Manual Operation
Optional external manual operator allows manual operation of the ATS with the door fully closed. This increases operator protection from arc flash.
