Description

Built to support older ITE and Siemens infrastructure, this 20A three-pole breaker fits legacy panelboards including FC-20 and CDP-6 models. It utilizes integral fuses to achieve a high-tier 200kAIC interrupting rating at 240VAC, offering exceptional current-limiting protection. While this specific C-Frame model is part of a legacy series, it remains essential for maintaining existing commercial systems. Note that the manufacturer designates the CED63B020 as its modern functional substitute.
