Product FAQs
6 answersWhat wire sizes are accepted by the standard lugs on the HFDE308033L?
The factory-installed line and load lugs accept copper or aluminum conductors ranging from 14 AWG to 1/0 AWG.
Which panelboards and equipment are compatible with this F-Frame breaker?
This unit mounts in Eaton Series C panelboards, motor control centers, and switchboards designed to accept F-Frame molded case circuit breakers.
What does the LS designation mean on the electronic trip unit?
The LS code indicates the electronic trip unit features adjustable Long-Time and Short-Time trip functions. This allows precise coordination with other protective devices in your electrical system.
What makes the HFDE frame different from a standard FDE breaker?
The H in the HFDE prefix designates a high-interrupting capacity version of the F-Frame. It provides up to 100 kAIC at 240 VAC and 65 kAIC at 480 VAC for systems requiring higher fault current protection.
Why choose an electronic trip unit over a thermal-magnetic breaker for this 80A application?
The electronic trip unit in the HFDE308033L provides more precise and adjustable trip curves compared to traditional fixed thermal-magnetic breakers. This is critical for complex motor control centers or switchboards requiring strict selective coordination.
How is the HFDE308033L mounted in the panel?
This is a unit mount, feed-thru circuit breaker. It bolts directly to the chassis or mounting pan of compatible Series C equipment rather than plugging onto a busbar.
