ABB SRPG400A300

The ABB SRPG400A300 is a rating plug designed for Spectra, Power Break, and Power Break II circuit breakers, allowing you to set or adjust the long-time trip point with ease. These interchangeable plugs offer great flexibility by letting you swap between different current ratings within the same breaker frame, making it a handy solution for various applications. Just a heads-up: since the rating plug determines the breaker's ampere rating, it's important to double-check that the connected cable or bus bar can handle the load. This matches how the National Electric Code lets you size cables according to the amp rating defined by the plug. Distributed by BSP Automation, the SRPG400A300 (sometimes listed as 783164213317) is a solid choice when you need adaptable protection settings without fuss.
