Product FAQs
7 answersWhat type of trip unit is installed in the FDE308033L?
This breaker features a Digitrip 310+ electronic trip unit with LS (Long-Time and Short-Time) protection. The 33 catalog suffix indicates it has an I2t response for the short delay time function.
What are the lug torque specifications for the FDE308033L?
For the standard slotted head terminals, torque values depend on the wire size: 35 lb-in for #14 to #10 AWG, 40 lb-in for #8 AWG, 45 lb-in for #6 to #4 AWG, and 50 lb-in for #3 to 1/0 AWG.
Does the FDE308033L come with lugs installed?
Yes, the L suffix in the catalog number indicates that this breaker is factory-equipped with both line and load terminals.
What equipment is the FDE308033L compatible with?
As a Series C F-frame breaker, it is designed for use in Eaton and Cutler-Hammer panelboards, switchboards, and motor control centers that accept F-frame unit-mount breakers.
What is the recommended torque for the mounting screws when installing this F-frame breaker?
When securing the breaker to the mounting surface, tighten the mounting screws firmly, but do not exceed 28 lb-in (3.16 N.m).
Can I field-install internal accessories in the FDE308033L?
No. Series C F-frame circuit breakers are factory sealed. Underwriters Laboratories (UL) requires that any internal accessories, such as auxiliary switches or shunt trips, be installed at the factory before the breaker is mounted and connected.
Does the electronic trip unit on this breaker include thermal memory?
Yes, the 310+ electronic trip unit incorporates a thermal memory feature that replicates the heating and cooling of the load during overload conditions, preventing power operation immediately after an overload trip.
