Square D SQU60111 – Frequently Asked Questions

1) Can the Square D C60 model 60111 breaker be used for branch circuit protection, or is it only supplementary?
Model 60111 in the Multi 9 C60 family is UL 489 Listed, so it qualifies as a branch circuit breaker rather than a supplementary protector. It also carries CSA C22.2 No 5 and EN/IEC 60947-2. If you only need supplementary protection downstream of a listed breaker, the ABB ST200M Series MCB is a UL 1077 device, which is a different listing and cannot be used where UL 489 branch protection is required.
2) What wire size will the Square D C60 60111 terminals accept?
The tunnel-type terminals at top and bottom take rigid conductors from 2.5 to 25 mm2, which is AWG 14 through AWG 4. Strip length is 14 mm and terminal torque is 2.5 N.m. That range covers typical 13 A branch wiring with plenty of headroom for oversized or parallel-run feeds into a control panel.
3) Is a C curve the right trip curve for motor or transformer inrush on a 13 A circuit?
The C curve on this C60 breaker trips magnetically at 8.5 x In plus or minus 20 percent on AC and 12 x In plus or minus 20 percent on DC, so at 13 A rated current that is roughly 110 A on AC before instantaneous trip. That tolerates the inrush of small motors, transformers and switch-mode supplies that would nuisance-trip a B curve. For purely resistive loads a lower curve is the better fit; for high-inrush equipment you would look at a D curve instead.
4) Can this Square D C60 breaker be used on DC circuits as well as AC?
Yes. Rated operational voltage covers 120 V AC nominal, with Ue extending to 240 V AC and 60 V DC, and the magnetic trip is specified separately for DC at 12 x In. Insulation voltage is 500 V AC with 6 kV impulse withstand and overvoltage category IV. Keep DC applications within the 60 V DC limit.
5) Is 10 kA interrupting capacity enough for my panelboard?
The C60 60111 is rated 10 kA breaking capacity at 120 V AC. That suits most commercial and OEM control panel locations, but it has to be at or above the available fault current calculated at that point in the system. Where a utility transformer puts more than 10 kA at the panel, you need a higher AIC device or a series-rated combination, such as a molded case breaker in the ABB A2 Series.
6) What is the difference between the Square D C60 UL489 miniature circuit breaker and the ABB ST200M miniature breaker?
Both are modular miniature circuit breakers with a C tripping curve, but they are listed to different standards. The Square D C60 is UL 489 listed, which is the standard for branch circuit protection in panelboards and distribution systems. The ABB ST200M is a UL 1077 supplementary protector, which is intended to protect a circuit downstream of a branch circuit device rather than serve as the branch circuit breaker itself. If a drawing or inspector calls for branch circuit protection, the UL 489 device is the one that satisfies it; a UL 1077 supplementary protector cannot be substituted for that duty.
7) Can I use an Eaton BAB Quicklag breaker instead of a Square D C60 UL489 MCB?
They mount in completely different ways, so they are not drop-in alternatives. The Square D C60 is a DIN rail mount modular breaker with an 18 mm connection pitch and tunnel-type terminals that accept AWG 14 to AWG 4 rigid conductors. The Eaton BAB Quicklag is a bolt-on thermal-magnetic breaker that fastens into a compatible loadcenter or panelboard interior. Use the C60 where you are building out a DIN rail distribution assembly or OEM control panel; use a bolt-on BAB where the existing panel interior is built for bolt-on breakers.
8) I need three-pole protection, not single-pole. What should I look at instead of the Square D C60 60111?
The C60 configuration under part number 60111 is a 1P device with one protected pole at 13 A. For three-pole duty there are several options depending on the frame you need: the Eaton BAB-302 is a three-pole Quicklag industrial thermal-magnetic breaker rated 240V, and for molded case frames the ABB A2A150TT is a 3-pole A2 Series molded case breaker, with the ABB XT4 and XT5 kits also supplied as 3-pole molded case units. Choose the molded case frames where the ampere rating and enclosure style exceed what a modular miniature breaker covers.
9) How much DIN rail space does the Square D C60 1-pole breaker take up?
It is a modular DIN rail device with an 18 mm connection pitch between adjacent devices, equal to 2 of the 9 mm pitch modules electricians count in panel layouts. Plan two modules per 1-pole breaker when you lay out the rail.
10) Can this breaker be locked out for maintenance?
The housing is padlockable and has ON/OFF signalling plus a contact position indicator, so you can verify the contacts are actually open and apply a lock for LOTO. It is also marked Suitable for Isolation per EN/IEC 60947-2, meaning it can serve as the isolating means for the circuit.
11) What is the difference between this DIN rail MCB and a bolt-on breaker like the Eaton BAB?
The Square D C60 is a modular MCB that clips onto DIN rail, which is how OEM control panels and industrial distribution boards are built. The Eaton BAB Quicklag is a bolt-on thermal-magnetic breaker that mounts to a panelboard interior instead, so the two are not interchangeable in the same enclosure. Pick by what the enclosure is prepped for: rail, or a bolt-on pan.
12) Is the 13 A rating on this breaker derated for panel temperature?
The 13 A line rated current is specified at 25 C ambient. In a crowded enclosure or a hot plant room the thermal element sees higher temperature and effective capacity drops, so size the breaker against the actual in-panel ambient rather than the 25 C figure.
13) Will this Square D breaker work as a replacement for a 3-pole molded case breaker?
No. The 60111 is a single-pole device protecting one pole, for DIN rail mounting. For a three-phase load you need a 3-pole breaker, and for molded case applications the ABB XT4 and XT5 Series 3-pole kits or the ABB A2N Series 3-pole molded case breaker are the right class of device.
14) Is a Bussmann CBC automotive circuit breaker an alternative to the Square D C60 MCB for a low-voltage DC circuit?
No. The Bussmann CBC is a Type I automotive circuit breaker rated 14VDC and is intended for vehicle and equipment wiring, with the CBC-B variant using a waterproof stud terminal. The Square D C60 is a UL 489 listed miniature circuit breaker for commercial and industrial panelboards, DIN rail mounted, with a rated operational voltage of 120 V AC and a Ue covering 240 V AC / 60 V DC and a 10 kA breaking capacity. The two serve different systems; an automotive Type I breaker does not provide branch circuit protection in a building distribution panel.
15) My application needs a higher ampere rating than the Square D C60 60111 provides. What frames should I be looking at?
Part number 60111 in the C60 range is a 13 A device, so for substantially larger loads you move out of the miniature breaker class into molded case frames. The Eaton 6602C72G67 is a Series C K-Frame mining circuit breaker rated 400A, 3-pole, with an interchangeable rating plug, and the ABB XT5 kit is a 3-pole circuit breaker kit in a larger molded case frame than the XT4. These are panel or enclosure mounted devices rather than DIN rail modular units, so plan the assembly accordingly.
16) Does the Square D C60 MCB accept an undervoltage release like the Eaton NZM breakers do?
The C60 is a thermal-magnetic modular breaker whose integrated indication features are an ON/OFF signalling contact and a contact position indicator, and the body is padlockable for lockout. Remote tripping accessories such as the undervoltage release offered for the Eaton NZM molded case series belong to that larger molded case platform. If the design requires an undervoltage trip function, specify a molded case frame built to take that accessory rather than a modular miniature breaker.
17) What ingress protection and temperature range does the Square D C60 MCB have?
Protection is IP40 when installed in a modular enclosure and IP20 at the device per IEC 60529, so it needs an enclosure in any dusty or wet location. Storage ambient is -40 to 80 C and it is rated for operating altitudes to 2000 m (6561.68 ft). Mechanical endurance is 20,000 cycles.
18) For a vehicle or mobile equipment panel, should I specify the Square D C60 or a Bussmann automotive breaker?
Specify the automotive family for vehicle work. Bussmann offers the CBF Series as a Type II automotive circuit breaker and the CBS Series as an automotive circuit breaker family, alongside the Type I CBC. The Square D C60 is built for modular DIN rail installation in commercial and industrial panelboards and OEM control panel assemblies, with tunnel terminals torqued to 2.5 N.m and an operating altitude rating to 2000 m. It is the right device for fixed building and control panel distribution, not for 12 V or 14 V vehicle circuits.
