V-TYPE PREPACKAGED TRANSFER SWITCHES

GENERAL ENCLOSURE

The prepackaged, V-Type transfer switch is rated 100 amps at 250 volts maximum. It is available in 2- pole configuration only and, for that reason, is useable with 1-phase systems only.

Prepackaged transfer switches do not have an intelligence system of their own. Instead, automatic operation of these transfer switches is controlled by a circuit board housed in the generator control panel.

The standard prepackaged, V-Type transfer switch enclosure is a NEMA 1 type ("NEMA" stands for "National Electrical Manufacturer’s Association"). Based on NEMA Standard 250, the NEMA 1 enclosure may be defined as one that is intended for indoor use primarily to provide a degree of protection against contact with the enclosed equipment and where unusual service conditions do not exist.
