Product FAQs
4 answersWhat does the L signify in the FDB2030L catalog number?
The L indicates that the breaker is supplied with both line and load side lugs installed from the factory.
Can the Eaton FDB2030L replace older Westinghouse FDB breakers?
Yes. Eaton acquired the Westinghouse molded case circuit breaker line. The FDB2030L is a direct replacement for legacy Westinghouse and Cutler-Hammer FDB breakers with the same specifications.
What does the LI trip function code mean on this breaker?
LI stands for Long-Time and Instantaneous trip functions. The long-time function provides thermal overload protection, while the instantaneous function provides magnetic short-circuit protection. Both are fixed and non-adjustable on this model.
How is a unit mount breaker like the FDB2030L installed?
As a unit mount, feed-thru molded case circuit breaker, it is typically mounted directly to a backpan or enclosure using screws, rather than plugging or bolting onto a panelboard bus.
