Description
Engineered for maximum system coordination, the FDE316036L is a 3-pole, 160A electronic trip circuit breaker in the Eaton Series C F-Frame family. This unit mounts into standard Eaton Series C panelboards, switchboards, and motor control centers for commercial power distribution. It utilizes a Digitrip 310+ unit with long-time, short-time, instantaneous, and ground fault (LSIG) functions. The breaker delivers a 35 kAIC rating at 480V, true RMS sensing, and current limiting capabilities.Specifications

Product FAQs
7 answersCan the FDE316036L replace older thermal-magnetic F-Frame breakers?
Yes, the FDE series shares the exact same physical footprint as standard Eaton Series C thermal-magnetic breakers, such as the FD, HFD, and FDC. This makes it a direct drop-in replacement when upgrading a panel to an electronic trip unit.
What is the adjustable continuous current range for this 160A breaker?
The Digitrip electronic trip unit allows the continuous current (Ir) to be adjusted from 60A up to the maximum 160A rating, providing precise overload protection for your specific load.
What are the torque specifications for the included line and load lugs?
For the standard 4 AWG to 4/0 AWG lugs, Eaton requires a tightening torque of 45 lb-in for 4 AWG wire, and 50 lb-in for 3 AWG through 4/0 AWG wire.
Can the FDE316036L be reverse fed?
Yes, Eaton FDE electronic circuit breakers are suitable for reverse-feed applications. Always verify that no voltage is present before servicing, as the line and load terminals will be energized differently than in standard top-feed configurations.
What does the 36L suffix in the catalog number indicate?
The 36 designates the Digitrip 310+ LSIG electronic trip unit, which includes Long-Time, Short-Time, Instantaneous, and Ground-Fault protection. The L indicates that the breaker comes factory-equipped with both line and load lugs.
How should the wiring be routed for single-phase ground fault applications?
Because this breaker features an LSIG trip unit with ground fault sensing, both the supply and return conductors must be routed through the breaker in single-phase applications. This ensures the trip unit can accurately monitor current balance and prevent nuisance tripping.
Which enclosures are approved for use with this F-Frame breaker?
The FDE316036L is designed for unit mounting in Eaton Series C panelboards, switchboards, and motor control centers (MCCs).
