OTPC 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 switch monitors both power sources, signals generator set startup, automatically transfers power, and returns the load to the primary power source when the utility returns and stabilizes.

OTPC transfer switches are available with closed transition transfer. By briefly connecting the two sources (for 100 msec or less), the transfer from the alternate source back to the normal source occurs without interruption in the power supply to loads.

  • PowerCommand® control - a fully featured microprocessor-based control with digital display. Controls allow operator to enter settings and make adjustments to software-enabled features easily and accurately. Accommodates up to eight event schedules.
  • Programmed transition - open transition timing can be adjusted to completely disconnect the load from both sources for a programmed time period, as recommended by NEMA MG-1 for transfer of inductive loads.
  • Advanced transfer switch mechanism - unique bi-directional linear actuator provides smooth, continuous transfer switch action during automatic operation.
  • Robust control system design - optically isolated logic inputs and isolation transformers for AC power inputs provide high-voltage surge protection.
  • Main contacts - heavy-duty silver alloy contacts with multi-leaf arc chutes are rated for 100% load interruption. They require no routine contact maintenance and provide 80% continuous current ratings.
  • Communications capability - the transfer switch is capable of communicating with other transfer switches, SCADA and remote monitoring systems, or Cummins Power Generation generators utilizing LonWorks® protocol.
  • Easy service/access - single-plug harness connection and compatible terminal markings simplify servicing. Access space is ample. Door-mounted controls are field-programmable; not tool is required.
  • All switches are UL 1008 Listed with UL Type Rated cabinets and UL Listed CU-AL terminals.
  • All switches are certified to CSA 282 Emergency Electrical Power Supply for Buildings, up to 600 VAC.
  • All switches comply with NFPA 70, 99 and 110 (Level 1), and NEMA ICS 10.
