SRPG400A400 | General Electric Rating Plug

The General Electric SRPG400A400 is a rating plug utilized in Spectra, Power Break, and Power Break II circuit breakers. These rating plugs are UL listed and offer interchangeability to set or modify the long-time trip point of the circuit breaker. The primary benefit lies in their ability to adjust the ampere rating across various current ratings within a specific circuit breaker frame. 

The General Electric SRPG400A400 rating plug is utilized across Spectra, Power Break, and Power Break II circuit breakers, employing UL listed interchangeable rating plugs to define or modify the long time trip point of the circuit breaker. This flexibility in rating plugs allows adjustments within the permissible current ratings of a specific circuit breaker frame, enhancing adaptability in various electrical applications. 

The primary advantage of the SRPG400A400 rating plug lies in its interchangeability, enabling convenient adjustment of circuit breaker trip points without replacing the entire breaker unit. This feature is particularly beneficial in scenarios where different current ratings are required within the same breaker frame, offering operational flexibility and cost efficiency. 

When installing the SRPG400A400 rating plug, it is crucial for the installer to ensure that the connected cable and/or bus bar ampacity are adequate for the established ampere rating. This verification process ensures compliance with safety standards and prevents overloading of electrical circuits. According to the National Electric Code (NEC), the ampere rating established by the rating plug dictates the permissible size of cables that can be safely connected to the circuit breaker.
