Product Description
GE Spectra Series Rating Plug
Introduction
The GE Spectra Series Rating Plug is an essential part of the Spectra breaker system, providing adaptability and interchangeability with various GE Spectra RMS circuit breaker frames.
Model Number Context
In the context of the model number, for example, 'SRPG600A500', the 'G' indicates the rating plug frame code, an important aspect for compatibility. This frame code can be denoted as 'G' for easy reference.
Functionality
Each rating plug adjusts the per unit (1X) continuous current rating of a breaker, operating similarly to an interchangeable trip unit in thermal-magnetic designs. With the appropriate rating plug installed, the long-time trip value of a breaker frame matches the ampere rating on the plug.
GE Spectra RMS motor circuit protectors use these rating plugs to fine-tune instantaneous and short-time pick-up values. Although these plugs do not offer low-level overcurrent protection, their role in customizing the breaker's operation is invaluable.
Installation
For instance, a breaker frame with a '600' amp sensor and an ' ' rating plug results in a '500' amp continuous current (long-time) rating. The breaker can be cabled or bussed to the rating plug ampere rating. Each rating plug is uniquely keyed to fit a specific circuit breaker frame and sensor rating.
Prior to installation, it's recommended to inspect the physical condition of the rating plug and confirm its compatibility with the breaker frame label. The correct engagement of the plug is indicated by an audible "click".
Enhanced Functionality
Reverse feeding on all frames is made possible through front-mounted internal accessories and rating plugs, enhancing the functionality of your GE Spectra RMS Circuit Breaker frames.
Conclusion
Whether you're upgrading your system or maintaining an existing setup, the GE Spectra Series Rating Plug range provides the versatility and reliability required.
