Carriere FB600ER2 Trip Unit

The designation FB600ER RMS TRIP FOR LA‑600A, CL in product listings clarifies its role as the tripping element that provides the residual‑magnitude protection characteristic required by these LA‑600A CL assemblies. Verified retailer and catalog entries depict the FB600ER2 with the 5‑2511‑0002 code, confirming it as a legitimate replacement trip unit for LA‑600A CL configurations with listings across multiple distributors. In practice, technicians install the FB600ER2 to restore proper tripping protection within LA‑600A CL assemblies in field service, and it is part of the Carriere FB600ER RMS trip unit family. For testing and maintenance, Carriere STS100 secondary‑injection testers are commonly used to evaluate FB600ER/FB600E trip units, including the FB600ER2, as part of commissioning or post‑fault verification in circuits protected by LA‑600A CL breakers.
