The UTP6ASD120GR is a universal three-phase automatic transfer switch designed to provide power transfer between different power sources. It is used in residential, commercial, and industrial applications to efficiently transfer power from one source to another, such as between a utility and generator, or between multiple utilities. The UTP6ASD120GR is designed for easy installation and can be operated with minimal skills. In addition, it is designed to handle high inrush current, enabling the load to be switched without the use of downstream breakers or contactors.

Application Field

The UTP6ASD120GR is widely used in residential, commercial and industrial power applications. In residential power installations, it is used to transfer power between a utility and a backup generator. Commercial applications include powering appliances and electrical equipment from multiple power sources. Industrial applications include powering machinery and other heavy machinery from separate power sources. In all applications, it is designed for high performance to ensure reliable power transfer.

Working Principle

The UTP6ASD120GR is designed to provide automatic transfer between two power sources, such as a utility and a generator. It uses one of two methods for transfer: transfer by time or transfer by voltage. The transfer is done by a set of three motor operated switches. When a source is lost, the switch starts to rotate until the other source is locked on. The UTP6ASD120GR also provides an output which can be used to open any downstream breakers or contactors before the transfer occurs. By monitoring the voltage and frequency of both sources, the switch can sense when one source has lost power and automatically start the transfer.

The UTP6ASD120GR also contains safety features to protect the switch and the connected equipment. It has time delay and current sensing protection to protect the switch from overloads. Additionally, the switching mechanism has built-in interlocks that prevent after-interrupting current and other dangerous occurrences. All relays used in the UTP6ASD120GR are flame-proof type ones, ensuring that there is no risk of fire due to hot arcing when the switch is operating.

The UTP6ASD120GR is an easy to maintain and install automatic transfer switch suitable for many applications. Its high-performance operation and safety features make it a reliable choice for multiple industrial and commercial applications.
