This document is a technical specification label for an electrical transfer switch, detailing its rating, usage, and safety parameters for various ampere and voltage configurations. The label provides comprehensive technical information about the transfer switch's capabilities, including maximum short circuit ratings, fuse classes, and acceptable load conditions. Key specifications include:

The transfer switch is rated for circuits delivering up to 100,000 RMS symmetrical amperes at 240 volts maximum, with multiple switch ampere ratings ranging from 225 to 1000 amperes. It is suitable for controlling motors, electric discharge lamps, tungsten filament lamps, and electric heating equipment. The switch transfers to an alternate power supply when normal voltage drops to 80% or when frequency reaches 58Hz, with optional voltage and frequency sensing. The label emphasizes periodic system testing and maintenance to ensure proper operating condition, and provides detailed guidance on fuse protection, circuit ratings, and operational parameters for different electrical configurations.
