Square D 60117 Multi9 C60 UL489 Miniature Circuit Breaker, D Curve, Tunnel Terminal

The Square D Multi9 C60 UL489 Miniature Circuit Breaker delivers reliable thermal-magnetic overcurrent protection for AC and DC electrical networks and motor branch-circuit applications. This D Curve MCB is available across a Motor FLA range of 0.5A, 1A, 2A, 6A, 10A, and 25A to match the full-load amperage of the motor or circuit being protected, so installers can select the correct rating for the application from a single trusted platform. Every option in the family shares the same tunnel-type terminal design, accepting 2.5-25 mm² (AWG 14...AWG 4) rigid conductors, and the same rated operational voltage range of up to 125 V DC / 240 V AC / 415 V AC / 440 V AC. Built to UL 489 and EN/IEC 60947-2 standards, this breaker is suitable for isolation and offers IP20 (IP40 in modular enclosure) degree of protection for demanding commercial and industrial installations.

Square D SQU60118 – Frequently Asked Questions

1) What wire size will the tunnel terminals on the Square D Multi9 C60 breaker accept?
The tunnel-type terminals take rigid conductors from 2.5 to 25 mm2, which is AWG 14 through AWG 4, and they can be landed from the top or the bottom. Tightening torque is 2.5 N.m, and the pitch between phases is 18 mm, so plan your wireway and phase spacing around that.
2) Is a D curve breaker the right choice, or should I use a B or C curve?
D curve is the high-inrush option. On the Multi9 C60 the magnetic trip limit is 12 x In on AC and 17 x In on DC, so it rides through the starting surge of transformers, motors and switch-mode supplies without nuisance tripping. If your load is resistive lighting or general receptacles, a lower curve trips faster on a fault and is the better pick. Choose D only where inrush is the problem you are solving.
3) Can I use the Multi9 C60 on a DC circuit as well as AC?
Yes. The C60 is rated for AC and DC networks, with rated operational voltages of 125 V DC, 240 V AC, 415 V AC and 440 V AC. That makes it workable for DC control and battery circuits up to 125 V as well as standard AC branch circuits.
4) Is this breaker UL 489 listed for branch circuit protection, or is it a supplementary protector?
It is a true branch-circuit device: UL Listed to UL 489, CSA certified to CSA C22.2 No 5, CCC certified, and compliant with EN/IEC 60947-2 and GB 14048.2. That matters because UL 1077 supplementary protectors cannot be used for branch circuit protection under the NEC. For comparison, the ABB ST200M miniature circuit breaker we carry is a UL1077 device, so it is not a substitute where a listed branch breaker is required.
5) Can an ABB ST200M miniature breaker be used in place of a Square D Multi9 C60 D curve breaker for branch circuit protection?
No. The Square D Multi9 C60 D curve breaker is built and listed to UL 489, which is the standard for branch circuit overcurrent protection. The ABB ST200M is a miniature circuit breaker to UL 1077, which covers supplementary protectors - devices intended to protect equipment downstream of a branch circuit device rather than to serve as the branch circuit breaker itself. If the drawing or inspector calls for branch circuit protection, the UL 489 device is the one that satisfies it; the ST200M would be the choice only where supplementary protection inside equipment is what is wanted.
6) When should I use a molded case breaker like the ABB A2N instead of a Square D Multi9 C60?
The Multi9 C60 is a DIN-rail miniature circuit breaker with tunnel-type terminals accepting AWG 14 to AWG 4 rigid conductors, rated to 25 A and used for branch circuit and modular panel work. The ABB A2A150TT is a 3-pole molded case circuit breaker in the A2 Series, a frame-style device bolted or plugged into a panelboard rather than snapped onto modular rail. Feeder and main positions, larger conductor sizes, and three-pole switching of a single common handle point to the molded case device; modular DIN-rail assemblies and smaller branch ratings point to the C60.
7) Which amperage ratings are available in this Square D Multi9 C60 D curve breaker?
Six ratings are offered: 0.5A, 1A, 2A, 6A, 10A and 25A, under part numbers 60117, 60118, 60120, 60124, 60193 and 60165. The low ratings suit control transformers and small motor circuits; 25A is the top of the group.
8) Can I lock out the Multi9 C60 for maintenance?
Yes, the handle is padlockable and there is an ON/OFF contact position indicator, so you can verify the contacts are open and secure it for lockout/tagout. It is also rated suitable for isolation per EN/IEC 60947-2, which is what lets it serve as the disconnecting means in that framework.
9) What enclosure rating do I need for this breaker in a plant environment?
On its own the C60 is IP20 per IEC 60529, which is finger-safe but offers no dust or water protection. Mounted in a modular enclosure it reaches IP40. For a dusty or washdown area you need to house it accordingly. Storage ambient is rated -40 to 80 C.
10) I need a 3-pole molded case breaker, not a DIN rail MCB. What else is there?
The Multi9 C60 is a modular miniature breaker, so for larger feeder duty look at a molded case unit instead. ZenSupply carries the ABB A2N Series 3-pole molded case breaker (UL Listed), the ABB E150 Series 3-pole thermal magnetic breaker, and the ABB XT4 Series 3-pole molded case kit. Those are the right family when the frame size or interrupting duty outgrows a DIN rail device.
11) What is the difference between the Square D Multi9 C60 and the ABB XT4 breaker kit?
The ABB MBB33 is an XT4 Series 3-pole molded case circuit breaker kit, meaning it is supplied as a kit built around the XT4 frame. The Square D Multi9 C60 is a single UL 489 miniature circuit breaker with tunnel terminals, a D curve trip characteristic, and a padlockable handle with ON/OFF contact position indicator. Buyers replacing an existing modular DIN-rail device stay with the C60; those working in an XT4 frame panel need the XT4 kit, as the two share no mounting or terminal interface.
12) How many operations is the Multi9 C60 good for if I switch it regularly?
Rated for 20,000 mechanical cycles and 10,000 electrical cycles. If you are using the breaker as a routine on/off switch for a load rather than purely as protection, the 10,000 electrical figure is the number to budget against.
13) What are the insulation and impulse withstand ratings on this MCB?
Rated insulation voltage (Ui) is 500 V AC and rated impulse withstand (Uimp) is 6 kV per EN/IEC 60947-2, with overvoltage category IV. Category IV is the origin-of-installation level, so it holds up at service entrance positions where transient surges are highest.
14) Is the Square D Multi9 C60 mercury free for our environmental spec?
Yes, the C60 is built mercury free, which clears most facility and institutional procurement restrictions on mercury-containing components. The housing is gray.
