Cummins Transfer Switch
100-600 Amps
Features & Benefits
- Installed by LT Generators
- Microprocessor control – Easy-to-use, standard control
- Programmed transition – Open transition timing can be adjusted to completely disconnect the load from both sources for a programmed time period
- Advanced transfer switch mechanism – Unique bi-directional linear actuator provides virtually friction-free, constant force, straight-line transfer switch action during automatic operation
- Manual operation – Manual operating handles, shielded termination, and over-center contact mechanisms
- Positive interlocking – Mechanical and electrical interlocking prevent source-to-source connection through the power or control wiring
- Main contacts – Heavy-duty silver alloy contacts with multi-leaf arc chutes are rated for 100% load interruption
- Easy service/access – Single-plug harness connection and compatible terminal markings simplify servicing
OTEC transfer switches are designed for operation and switching of electrical loads between primary power and standby generator sets. The switches monitor both power sources, signal generator set startup, automatically transfer power, and return the load to the primary power source once a stable utility is available.
Features
Microprocessor Control: Easy-to-use, standard control, LEDs display transfer switch status, push buttons allow operator to activate control test, exercise timing and transfer mode.
Programmed Transition: Open transition timing can be adjusted to completely disconnect the load from both sources for a programmed time period.
Positive Interlocking: Mechanical and electrical interlocking prevent source-to-source connection through the power or control wiring.
Easy Service/Access: Single-plug harness connection and compatible terminal markings simplify servicing. Access space is ample. Door-mounted controls are field-programmable, no tool is required.
