Automatic Transfer Switches

Used for switching power between the primary (utility) and secondary (backup or supplemental) power sources, Cummins automatic transfer switches feature Power Command control technology for easy operation and a robust, high-contact force design to withstand thousands of switching cycles. A full line of standard switches are available from 40 to 40,000 amps for the entire range of power systems.

The GTEC automatic transfer switch, another Cummins manufactured product, combines reliability and flexibility in a small, economical package for normal and generator set source monitoring, generator set starting and load transfer functions. Automatic transfer switches are ideal for IEC emergency, standby and optional standby applications.

Power Command Control Microprocessor-based controls are developed specifically for automatic transfer switch operation.

Robust control system design Optically-isolated logic inputs and high isolation transformers for AC power inputs

Communications capability

Transfer switch communications via a SCADA network or LonWorks

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.

Break-before-make action

Independent break-before-make action is used for both 3-pole and 4-pole/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.

Mechanical interlock

 Prevents simultaneous closing of normal and emergency contacts.
