ABB A2A200TT – Frequently Asked Questions

1) Which ABB A2 Series breaker models are available and how do I pick the right amp rating?
The ABB A2 Series molded case breakers here run across eight models: A2A125TL-2, A2A150TL-2, A2A200TL-2, A2A150TT, A2A175TT, A2A200TT, A2A225TT, and A2N150TT. The amperage rating spans 150-1500A across the platform. The number in the model is your handle on the rating, so order by exact part number to match the feeder or branch circuit you are protecting rather than by series alone.
2) Is the ABB A2N breaker a 3-pole unit suitable for three-phase distribution?
It is a 3-pole breaker, which is what you want for balanced three-phase feeder and branch protection. If your circuit is single-phase or you need to switch only one or two ungrounded conductors, this is the wrong configuration.
3) What kind of trip unit is in the ABB A2N breaker, electronic or thermal-magnetic?
Thermal-magnetic. The A2N is built with a TMF thermal-magnetic fixed trip unit handling both overcurrent and short-circuit protection. If your spec calls for an electronic trip unit with adjustable long-time, short-time and instantaneous settings, a thermal-magnetic frame will not satisfy it.
4) What is a comparable thermal-magnetic molded case breaker to the ABB A2N from another brand?
The closest equivalent we carry is the Square D PowerPacT B thermal magnetic circuit breaker, which uses the same trip technology as the A2N's TMF thermal-magnetic unit. If your gear is I-Line bussed rather than bolt-on, the Square D PowerPacT Q I-Line breaker is the one that plugs into that busbar system; the ABB A2 frame will not drop into an I-Line panel.
5) What is the closest cross-brand equivalent to the ABB A2N 3-pole molded case breaker?
The nearest equivalent from Square D is the PowerPacT B thermal magnetic circuit breaker. Both are molded case breakers using thermal-magnetic trip technology, the same protection method as the A2N's TMF thermal-magnetic fixed trip unit. Confirm the frame ampere rating and interrupting rating you need against the PowerPacT B frame before substituting, since the ABB A2 Series models span a 150-1500A adjustable trip range across 3-pole configurations.
6) If I am feeding an I-Line panelboard instead of a bolt-on mounting, what should I use instead of the ABB A2N?
Use the Square D PowerPacT Q I-Line circuit breaker. I-Line is a plug-on bus connection system specific to Square D I-Line panelboards, so the breaker lands on the bus rather than using bottom-mounted terminations. The ABB A2N is configured with the KA2225 BOT bottom-mounted accessory option for panelboard and switchgear connections, which is a different termination approach and will not plug onto an I-Line bus.
7) What is the KA2225 BOT option on the ABB A2 Series breaker?
KA2225 BOT is the bottom-mounted accessory configuration for the A2 Series, covering application-specific bottom connections and terminations in panelboard and switchgear enclosures. It matters when your incoming or outgoing cable routing dictates which end of the breaker the connectors sit on, so confirm your cable entry direction before you settle on the accessory configuration.
8) Is a molded case breaker like the ABB A2N the right choice, or do I need a DIN rail miniature breaker?
Molded case is the frame you use for feeder and branch protection in panelboards and switchgear, and the A2N is a 3-pole molded case unit. For control panel and small branch work on a DIN rail, a miniature breaker is the better fit, such as the Square D C60 UL489 miniature circuit breaker, which is a DIN rail mount device, or the Square D Multi9 C60 1-pole C-curve MCB rated 120V AC for single-pole lighting and receptacle circuits.
9) Can I use the ABB A2N breaker for motor circuit protection?
Motor control and load center wiring is among the applications the A2N is built for, alongside feeder and branch circuits in commercial and industrial distribution. It is a 3-pole thermal-magnetic frame, so it suits three-phase motor feeders; size it to the motor load per your circuit design.
10) I need a DIN rail mounted UL 489 breaker, not a molded case unit. What is the alternative?
The Square D C60 UL489 miniature circuit breaker is a DIN rail mount device, which suits control panels and equipment enclosures built around DIN rail. The ABB A2N is a molded case breaker that mounts in panelboards and switchgear and carries a UL Listing, with the KA2225 BOT bottom-mounted accessory option for its connections. Pick by how the enclosure is built out, then match the ampere and interrupting requirements.
11) Does the ABB A2N breaker ship as a single unit or in a multi-pack?
Each order is 1 each, a single breaker. That works for a one-for-one replacement in an existing panel or for counting out new construction quantities line by line.
