Description
Designed for standalone unit mounting, this 160-amp Eaton MCCB delivers reliable power distribution for industrial facilities. Equipped with both line and load lugs, the F-frame breaker integrates into Series C motor control centers and switchboards without requiring a specialized panelboard chassis. It replaces the FDCE316035L. The integrated Digitrip 310+ module provides microprocessor-based LSG protection, ensuring accurate true RMS sensing and a 65kAIC interrupt rating at 480V.Specifications

Product FAQs
6 answersWhat panels and enclosures are compatible with the HFDE316035L?
This F-frame breaker is designed for use in Eaton Series C panelboards, motor control centers, and switchboards. It is also backwards compatible with many legacy Cutler-Hammer and Westinghouse F-frame installations.
What does the LSG trip function indicate on this breaker?
The 35 in the catalog number designates an electronic trip unit with Long-Time, Short-Time, and Ground-Fault (LSG) protection. This allows for precise coordination and protects equipment from low-level arcing faults.
What is the difference between the FDE and HFDE frame types?
The H in HFDE indicates a high-interrupting capacity version of the standard FDE frame. While a standard FDE breaker provides 35 kAIC at 480V, the HFDE provides up to 65 kAIC at 480V for systems with higher fault current potentials.
Does the HFDE316035L come with factory lugs?
Yes, the L at the end of the catalog number indicates that factory line and load lugs are included. These terminals accept 4 AWG to 4/0 AWG copper or aluminum conductors.
How does the ground-fault feature on this breaker improve system safety?
The electronic trip unit includes adjustable ground-fault pickup and delay settings. This protects equipment from low-level arcing faults that standard thermal-magnetic breakers might not detect, reducing fire risks and equipment damage.
Can the HFDE316035L replace older Westinghouse F-frame breakers?
Yes, Eaton Series C F-frame breakers share the same physical footprint as legacy Cutler-Hammer and Westinghouse F-frame breakers, making them suitable for direct replacement in existing enclosures.
