➋ Motor Control Center Replacement Breakers do not have the same physical dimensions or mounting holes as the breakers they replace. Types RMCFA
and RMCHFA are 6 inches long and the breakers they replace, FA and HFA, are 6 1 ⁄2 inches long. Types RMCF and RMCHF are 6 inches long and the breakers
they replace, F and HF, are 9 3 ⁄8 inches long. A mounting plate is provided with each breaker to resolve these differences, and must be installed to ensure
a proper fit.
➌ Motor Control Center Replacement Circuit Breakers have non-interchangeable trip units and the same interrupting capacity as the out-of-production circuit
breakers they replace.
➍ RMCFA and RMCHFA 2-pole breakers are supplied in a 3-pole frame with current carrying parts omitted from the center pole.
