ABB TM-24415R Main Breaker Load Center, Outdoor Enclosure

The ABB TM-24415R main breaker load center is available in amperage options from 150A to 200A and in 1-phase or 3-phase configurations, giving electricians a factory-installed main breaker for a fast, convenient install and a single point to shut off all power in the building. This load center offers 24 spaces for 1" breakers, is housed in an outdoor-suitable enclosure, and measures 33.2 in overall, making it a solid choice for commercial and light-industrial main-service applications where a 208Y/20V distribution system is in use.

Key Features

  • Factory-Installed Main Breaker: Ships with the selected 150A or 200A main breaker in place, allowing the user to shut off all power to the structure from a single point and speeding up installation.
  • 24-Space Configuration: Offers 24 spaces for 1" breakers, providing ample circuit capacity for demanding commercial distribution needs.
  • Selectable Phase Configuration: Available in 1-phase or 3-phase configurations to match the site's power distribution requirements.
  • Outdoor-Suitable Enclosure: Built to be installed outdoors, protecting the internal breakers and bus assembly from the elements.
  • Top Feed Configuration: Feeders are located at the top of the enclosure, simplifying conduit routing during installation.
  • Interrupt Rating: Rated to an interrupt rating of 22 for demanding fault-current conditions.
  • Voltage Rating: Rated for 208Y/20V systems.
  • Compact Overall Size: Overall enclosure size of 33.2 in keeps the footprint manageable for main-service installations.

Why ABB?

ABB's TM-24415R main breaker load center family combines a factory-installed 150A or 200A main breaker, a 24-space configuration available in 1-phase or 3-phase, and an outdoor-suitable enclosure built to the UL standard, giving contractors a dependable, code-conscious option for main electrical service work. The convenience of a pre-installed main breaker reduces install time while still delivering the circuit capacity commercial projects demand across a range of amperage and phase options.

ABB TM2415RCU – Frequently Asked Questions

1) Does the ABB TM24420C load center come with the main breaker already installed?
Yes. The TM24420C ships with a 200A main breaker factory installed, so there is no separate main to buy or mount. That gives the building a single point to kill all power and saves install time on a service replacement or new main service.
2) Is the ABB TM24420 panel single-phase or 3-phase, and what voltage system does it work on?
The TM24420C is a 3-phase load center rated 208Y/20V. If your service is single-phase, order the TM2415RCU instead, which is the 150 amp single-phase version. There is also a 150 amp 3-phase model, the TM24415R.
3) Can this ABB main breaker load center be mounted outside?
Yes, the enclosure is built for outdoor installation, so it can go on an exterior wall at the service entrance without a separate weather housing. It is UL listed.
4) Can I use a Square D Homeline or QO panel outdoors instead of the ABB TM24420C?
Not in the same spot. Both the Homeline 225A main lugs and the QO plug-on neutral load center are NEMA 1 enclosures, which are indoor only. For an exterior service entrance you need the outdoor-rated enclosure the ABB TM24420C comes in.
5) What is the difference between an ABB TM24420C load center and a Square D Homeline main lugs load center?
The difference is the disconnect. The ABB TM24420C ships with a 200A main breaker already installed, so the structure has a single point to shut off all power. The Square D Homeline L225PC is a convertible main lugs load center, meaning it arrives with lugs rather than a factory main breaker and relies on an upstream disconnect unless a main is added. The ABB unit is also configured for 3-phase at 208Y volts in an outdoor-suitable enclosure, while the Homeline L225PC is a NEMA 1 enclosure intended for indoor, dry locations, and it is built around 60 spaces for 120 circuits versus 24 spaces for 1 inch breakers on the ABB.
6) I need a load center for an outdoor service entrance - is the Square D QO plug-on neutral panel an option?
For an outdoor location it is not the right pick. The Square D QO convertible main lugs load center is a NEMA 1 enclosure, which is an indoor dry-location rating, and it is a main lugs panel rather than one with a factory main breaker. The ABB TM24420C is built in an outdoor-suitable enclosure with a 200A main breaker installed and top-located feeders that simplify conduit routing into a service entrance, and it is UL listed. If the panel is going on an exterior wall, the ABB unit is the one configured for it.
7) My job is single-phase, not 3-phase. What should I use instead of the TM24420C?
The TM24420C is the 3-phase, 200 ampere configuration. Within the same ABB TM series there is a TM2415RCU built for single phase at 150 amperes, which is the direct move if the service is single-phase. If the panel is going indoors and an upstream disconnect already exists, the Square D QO convertible main lugs load center with plug-on neutral is another direction, though it is a NEMA 1 indoor enclosure and comes as main lugs rather than with a main breaker installed.
8) Do Homeline or QO breakers fit an ABB TM24420C load center?
No. The Square D Homeline L225PC and the Square D QO panel are built around their own breaker series - Homeline and QO respectively - and those are not interchangeable with the ABB TM series bus. The TM24420C accepts 24 spaces for 1 inch breakers on the ABB 3-phase bus assembly. If a facility is already standardized on Homeline or QO breakers for stock reasons, that is a real argument for staying inside one of those Square D panels; if the panel is going outdoors with a factory main breaker, the ABB unit is the one that fits that opening.
9) How many breaker spaces does the ABB TM24420C have?
24 spaces sized for 1 inch breakers. On a 3-phase panel that works out to eight 3-pole circuits if you fill it with three-pole breakers, or a mix of single and multi-pole loads across the same 24 spaces.
10) Where do the feeders enter this ABB load center, top or bottom?
Top feed. The feeders land at the top of the enclosure, which suits a service drop or overhead conduit run. If your service conductors come up from below, plan the conduit run accordingly before you set the can.
11) What is the interrupt rating on the ABB TM24420C, and is it enough for a commercial service?
It carries an interrupt rating of 22, which is what you want to check against the available fault current the utility gives you at the service point. Confirm that number against the utility letter before you set a 200A main.
12) I need more than 24 circuits. What else could I use instead of the ABB TM24420C?
If circuit count is the driver, the Square D Homeline 60-space 120-circuit 225A load center gives far more capacity, but it is a main lugs unit in a NEMA 1 enclosure, which means indoor mounting and a separate upstream disconnect. The ABB TM24420C stays the right call when you need the main breaker in the panel and the panel outdoors.
13) Is there a 150 amp version of this ABB outdoor load center?
Yes. Two lower-amp options exist: the TM24415R at 150 amps 3-phase, and the TM2415RCU at 150 amps single-phase. The 200 amp model is the TM24420C, 3-phase. Size the panel to the calculated service load, not the space count, since all three carry the same 24 spaces.
14) I need far more branch circuits than 24 - what load center handles that?
The ABB TM24420C is a 24-space panel for 1 inch breakers, which covers most commercial main-service distribution but caps out there. For a much higher circuit count, the Square D Homeline L225PC is a 60-space, 120-circuit convertible main lugs load center rated 225A. Note the trade-offs before switching: it is a NEMA 1 enclosure rather than outdoor-suitable, it is supplied as main lugs rather than with a main breaker installed, and it uses the Homeline breaker series.
15) What is the plug-on neutral feature on the Square D QO panel, and does the ABB TM24420C have it?
Plug-on neutral is a bus design on the Square D QO convertible main lugs load center that lets GFCI and AFCI breakers land their neutral connection directly on the bus instead of through a pigtail wire to the neutral bar, which cuts wiring time when a panel is loaded with those breakers. The ABB TM24420C is described by its factory-installed 200A main breaker, 3-phase 208Y configuration, top feeders and outdoor-suitable enclosure - it is aimed at main-service disconnect duty rather than at a dwelling-unit panel full of AFCI branch breakers.
16) How big is the ABB TM24420C enclosure?
Overall size is 33.2 inches, so figure that into your wall space and your working clearance at the service entrance.
