Product Usage

Transfer switches are devices that are essential for emergency power electrical installations when generators are used. Whether your application is industrial or commercial in nature, power supply continuity and electrical distribution is critical. A manual transfer switch allows you to start a generator when utility power fails and restore power to predetermined circuits. This is a reliable, simple, and cost-effective method to provide building owners with a high level of safety and security.

Three-way manual transfer switches (also called three-phase or three-pole) offer the option to get power from the utility grid or from generators, or to leave the system in neutral.

Manual transfer switch breaker/breakers offer emergency power solutions in a variety of applications, including:

  • Lift stations
  • Gas stations
  • Data centers
  • Grocery and retail
  • Water/wastewater facilities
  • Health care facilities
