Description
Engineered for commercial and industrial applications, this 25A two-pole breaker provides thermal-magnetic protection for 600VAC systems. It serves as a robust component within the legacy F-Frame family. This bolt-on unit installs into Siemens FCI, FCII, CDP-6, SB1, SB2, and SB3 panelboards, as well as S5 and P5 switchboards. For modern upgrades, it is replaced by the ED62B025, which requires specific mounting hardware.Specifications
