Abb srpg400a400 Rating Plug 400A 480VAC Spectra Series

Product Description

The ABB srpg400a400 is a UL listed interchangeable rating plug designed for use with Spectra Series, Power Break, and Power Break II circuit breakers. It establishes the long time trip point of the circuit breaker at 400 amps, with a trip range of 1210 to 4080. Rated for 480 volts AC, this plug sets the ampere rating of the breaker frame, making it a critical component in determining the protection level of the circuit. Licensed electricians install rating plugs during commissioning or when adjusting breaker ratings within a given frame size.

This rating plug is used in commercial and industrial power distribution applications where Spectra Series, Power Break, or Power Break II circuit breakers are installed. The interchangeable design gives installers flexibility to set or change the current rating across permissible ratings within the same breaker frame. Because the rating plug establishes the breaker ampere rating, the connected cable or bus bar ampacity must be verified to match. The National Electrical Code permits cable sizing to correspond to the ampere rating set by the installed plug.

Key Features

• 400A long time trip point rating for compatible circuit breaker frames
• Rated for 480 volts AC service
• Trip range of 1210 to 4080
• UL listed interchangeable design allows rating changes within the same frame
• Compatible across Spectra Series, Power Break, and Power Break II platforms

Compatibility

Designed for use with ABB Spectra Series, Power Break, and Power Break II circuit breakers that accept interchangeable UL listed rating plugs within the permissible current ratings of the breaker frame.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code. The circuit breaker must be fully de-energized and isolated before removing or installing a rating plug. After installing the plug, verify that all connected cable and bus bar ampacity meets or exceeds the 400A rating established by the plug. Do not install this plug in a frame size for which it is not rated.
