FJA34020 - 20Amp Circuit Breaker

FJA34020 Molded Case Circuit Breaker | 20 Amp 3-Pole FJA Frame, I-Line Plug-In

The FJA34020 is a 20 Amp, 3-pole molded case circuit breaker designed for your electrical distribution equipment that uses an FJA frame I-Line connection. It is commonly used in commercial and industrial installations where an existing plug-in breaker needs to be replaced with one that matches the original frame type, mounting style, and electrical ratings. Keeping these details consistent helps maintain the existing equipment layout and avoids unnecessary changes to the system.
