OTEC 40-1000 amp series automatic transfer switches The OTEC series transfer switch provides the basic features you need for primary source and generator set monitoring, generator set starting and load transfer functions for emergency standby power applications.
OTEC transfer switches are
designed for operation and switching of electrical loads between primary power
and standby generator sets. They are suitable for use in emergency, legally
required, and optional standby applications. The switches monitor both power
sources, signal generator set start up, automatically transfer power, and
return the load to the primary power source once a stable utility is available.
The fully integrated controller is designed for practical functionality, with
LED indicators and digital push buttons for ease of operator use.
-Easy service/access
Plug connections, door-mounted controls, ample access space, compatible terminal
markings simplify access
-Advanced transfer switch mechanism
Bi-directional linear motor actuator provides virtually friction-free, constant-force,
straight-line transfer switch action with no complex gears or linkages

Independent break-before-make action is used for both 3-pole and 4-ppole/switched
neutral switches
-Main contacts
Heavy-duty silver alloy contacts with separate arcing surfaces and multi-leaf
arc chutes are rated for total system transfer including overload interruption
