Highlights:
RX2E starters provide solid state reduced voltage starting for normal
operation and full voltage emergency backup starting with complete
electronic motor protection at the flip of a switch. This unique redun-
dant design is the ideal solution for critical applications where down-
time is extremely disruptive to production operations and cannot be
tolerated. Benshaw’s MX solid state controls provide precise digital
starting and stopping, motor protection, metering, diagnostics and
communications.
Units are stocked with MX
2
technology, but are available with MX
3
technology.
