Product Overview
Two-Pole Schneider Multi 9 C60 D 3A Breaker, 480Y/277V, Made in France
Condition
Used and clean. The photographs show a two-module device with both toggles sitting at 0 OFF and joined by a factory handle tie. The housing is free of cracks, chips, or heat discoloration, and the Schneider Electric label with its green band is sharp and fully legible: D 3A, 480Y/277V, C60, Multi 9, 24518. Terminal screws top and bottom are bright and their crossheads look undamaged. One flank carries the molded Merlin Gerin logo, the barcode 0 785901 881162, and Made in FRANCE all together; the opposite flank carries the molded rating block. There is one faint pinkish surface mark along the top edge of the label face, the kind of paint or marker trace a device picks up in a panel, and the DIN clip on one module sits in the released position.

Product Overview
Multi 9 C60 is the DIN rail miniature circuit breaker line Schneider Electric carried forward from Merlin Gerin, and this is the D curve 3A version, catalog number 24518, built two poles wide with a common handle tie across both toggles. The D in the front marking D 3A is the trip curve designation printed on the case; D curve devices in this family are the ones normally specified for higher inrush loads, and you should verify the published curve for 24518 against your own coordination requirements before use. The side of the case carries the full rating block, which the photos read clearly: SC:10kA C1 240V and SC:5kA C1 480Y/277V, OL0 TC2 FW3, SUPPL PROT, CU ONLY, 75C Cu wire at 22 lbf.in (2.5 N.m), MAX 300V to ground, IEC 60947-2 50/60Hz and GB14048.2 50Hz 25C, CatA with Ics=75%Icu, Ue=240V Icu=20kA, Ue=415V Icu=10kA, and Uimp=6kV. SUPPL PROT is the supplementary protector designation, so confirm what your circuit and your local code actually require before putting this in a branch circuit position.

Applications
- Controls technician rebuilding a machine panel who needs the exact 3A D curve two-pole device the original Multi 9 lineup was drawn around
- Maintenance electrician keeping an older Merlin Gerin DIN rail assembly intact instead of redesigning the whole row around a new frame
- Panel builder who has two module widths of rail to fill and wants a tied two-pole unit that drops straight in
- OEM service group stocking spares for equipment that shipped with Multi 9 breakers and needs catalog number 24518 to match on paper
Frequently Asked Questions
How many poles is this, and how much rail does it take?
Two poles. The photos show two modules with a factory tie bar across both toggles, so it occupies two standard DIN module widths and both poles move together. Measure the free space in your row before ordering.
What do the SUPPL PROT and SC markings on the side mean for my install?
The case is marked SUPPL PROT, the supplementary protector designation, with SC:10kA C1 at 240V, SC:5kA C1 at 480Y/277V, and MAX 300V to ground. If your application calls for a UL 489 branch circuit breaker, this marking is telling you this is a different class of device. Verify against the current Schneider documentation for 24518 and your local code before you install it.
What wire and torque does the case call for?
The molded text reads CU ONLY and 75C Cu WIRE TORQUE 22 lbf.in (2.5 N.m). Copper conductors only, 75C rated, and a torque screwdriver set to 22 lbf.in. That figure is a case marking, not our measurement, so confirm it against the datasheet if your inspector wants a documented value.
Is this a Schneider part or a Merlin Gerin part?
Both names are on this one breaker. Schneider Electric is printed on the front label, Merlin Gerin is molded into the side. Multi 9 began as a Merlin Gerin line and continued under Schneider, so drawings, spares lists, and old panel schedules may reference either brand against the same 24518 catalog number.
It is listed as used - what am I actually getting, and what am I taking on?
A used breaker, sold on its markings and these four photographs. It has not been trip tested, no timing curve was run, and no insulation or contact resistance reading was taken here, so the printing on the front, the rating block on the side, and the photos are the spec. What the photos do show is a clean, uncracked housing, fully legible D 3A / 480Y/277V / C60 / Multi 9 / 24518 printing, undamaged terminal screws, and an intact DIN clip. If your job needs a documented, factory-tested device, buy new; if you are matching an existing Multi 9 lineup and will verify the unit on your own bench, this used one is worth a look. Shipping is $8 flat rate and free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
Schneider on the face, Merlin Gerin molded into the barcode flank right beside Made in FRANCE: one small breaker carrying two company names and both toggles still parked at 0 OFF where somebody left them. Prove it out on your bench, then give it two slots on the rail and let it get back to work.
