B-LINE FDB2150 – Frequently Asked Questions
1) What is the interrupting rating of the Eaton FDB2150 breaker at 240V and 480V?
The FDB2150 is rated 18 kAIC at 240 Vac and 14 kAIC at 480 Vac. If your available fault current at the panel exceeds those numbers, this FDB frame won't satisfy the short circuit requirement and you need a higher AIC F-frame class such as an FD or HFD.
2) Is the FDB2150 a two-pole 150 amp breaker, and what voltage can it be applied at?
Two poles, 150 amps, with a rating of 600 Vac or 250 Vdc and 50/60 Hz operation. That covers a 240V single-phase load or a two-pole tap off a 480V three-phase system.
3) Is the trip unit on the FDB2150 adjustable?
No. It uses a fixed thermal, fixed magnetic trip unit, so there is no dial to set the instantaneous or long-time pickup. Ordering it means accepting the 150 A trip point as built. If your coordination study calls for an adjustable instantaneous setting, specify an F-frame breaker with an adjustable magnetic trip instead.
4) Does the FDB2150 come as a complete breaker or do I have to add a trip unit?
It ships as a complete molded case breaker in the FDB type, F-frame, Eaton Series C. Nothing separate to assemble on the trip side. Lugs are load side terminals, so plan your line side connection accordingly for the panel or enclosure it's going into.
5) What are the dimensions and weight of the FDB2150 for enclosure and panel layout?
Measures 3.38 in length by 2.75 in width by 2.75 in height and weighs 3 lb. Use those figures when checking gutter space and mounting pattern in an existing enclosure before you pull the old two-pole out.
6) Can the FDB2150 be used on a 250 volt DC circuit?
Yes, it carries a 250 Vdc rating alongside the 600 Vac rating, so DC applications up to 250 volts are within its published rating. The AIC figures published for it are AC values at 240 and 480 volts.
7) What is the exact part number to order this Eaton 150 amp F-frame breaker?
The manufacturer part number is FDB2150. In Eaton's F-frame nomenclature the FDB prefix identifies the lower interrupting rating version of the frame, the 2 is the pole count and 150 is the amp rating, so FDB2150 is the two-pole 150 A unit.
