ABB A2A200TW-2 – Frequently Asked Questions

1) What is the difference between the ABB A2A and A2N breaker models in the A2 Series 250 frame?
Both are ABB A2 Series molded case breakers on the 250 frame with a TMF thermal-magnetic fixed trip unit, and the letter after A2 is the interrupting rating class ABB assigns to the frame. Orderable models are A2A200TW, A2A200TW-2, A2A225TW-2, A2N200TW and A2N225TW. Pick the A or N class your panel schedule or coordination study calls for, then the amp rating (200 or 225) to match the circuit.
2) Can I use the ABB A2N 250 TMF breaker to protect a three-phase circuit?
Yes. It is built as a 3-pole device, so it breaks all three phase conductors of a three-phase circuit together. For single-phase or two-wire loads you want a 1-pole or 2-pole breaker instead, not this one.
3) Is the ABB A2 Series 250 frame breaker UL Listed for a code-compliant commercial install?
The A2N 250 TMF is UL Listed, which is what an AHJ or an institutional spec normally requires for overcurrent protection in commercial and industrial distribution equipment. That listing is the only certification carried on it.
4) Can I adjust the trip setting on the ABB A2N 250 TMF breaker?
No. TMF means thermal-magnetic fixed, so both the thermal overload and magnetic short-circuit trip points are set at the factory and cannot be dialed in the field. If your coordination study needs an adjustable magnetic pickup or an electronic trip unit, this is the wrong trip type and you need a different A2 Series trip configuration.
5) Will this ABB breaker drop into my existing A2 Series panel, or do I need a plug-in version?
This one is fixed-fixed (F F) mounting, meaning it bolts in as a fixed-mount device in compatible A2 Series switchgear and enclosures. It is not a plug-in or draw-out breaker. If the existing gear is prepped for a plug-in or withdrawable cassette, a fixed-mount breaker will not seat in it.
6) I need to replace a failed breaker in existing ABB A2 gear. What do I have to match?
Match four things off the label of the breaker coming out: the frame (A2 250), the class letter (A or N), the pole count, and the amp rating. On this family that lands you at A2A200TW, A2A200TW-2, A2A225TW-2, A2N200TW or A2N225TW, all 3-pole thermal-magnetic fixed devices in fixed mounting. Miss the class letter and you can end up with an interrupting rating below what the panel schedule requires.
7) Can a DIN rail miniature circuit breaker be used instead of the ABB A2N 250 TMF 3P?
No. The Square D C60 UL489 miniature circuit breaker is a DIN rail mount MCB, a different device class from the ABB A2N 250 TMF. The ABB breaker is a molded case circuit breaker built on the A2N 250 frame with fixed-fixed mounting into compatible A2 Series switchgear, not a DIN rail device. If the enclosure has a DIN rail and small branch circuits, the C60 is the correct style; if the equipment is an ABB A2 Series panelboard or switchboard, the A2 molded case breaker is what the interior accepts.
8) What is the closest thermal-magnetic molded case breaker to the ABB A2N 250 TMF if I need a different brand?
The Square D PowerPacT B is a thermal magnetic molded case circuit breaker and is the nearest same-type alternative to the ABB A2N 250 TMF. Both are thermal-magnetic molded case devices rather than miniature breakers. The ABB unit is a 3-pole, fixed-fixed mount device on the A2N 250 frame within ABB's A2 Series, so it drops into A2 Series panelboards and switchboards directly; the PowerPacT B is a Square D frame and follows Square D mounting and interior arrangements, meaning a change of brand is a change of equipment interface, not just a change of label.
9) How does the ABB A2N 250 TMF compare to a Square D PowerPacT Q I-Line breaker?
Both are molded case circuit breakers, but they are built for different equipment. The Square D PowerPacT Q is an I-Line breaker, meaning it plugs onto Square D I-Line bus stabs in I-Line panelboards and switchboards. The ABB A2N 250 TMF uses fixed-fixed mounting on the A2N 250 frame for installation into compatible ABB A2 Series equipment. They are not interchangeable in the same enclosure; match the breaker to the bus and interior you already have.
10) What else does ZenSupply carry if I need a thermal-magnetic molded case breaker but not an ABB frame?
The Square D PowerPacT B thermal magnetic circuit breaker is the closest peer we carry, same thermal-magnetic molded case approach in a different manufacturer's frame. There is also the Square D PowerPacT Q I-Line breaker if your gear is I-Line bus-mount. Keep in mind breaker frames are not cross-brand interchangeable, so the enclosure or panelboard decides which family you can use.
11) I only need single-phase branch protection, not three-phase. What should I look at instead of the ABB A2N 250 TMF 3P?
The ABB A2N 250 TMF is a 3-pole device intended for three-phase circuit protection. For a single-pole 120V AC branch circuit, the Square D Multi9 C60 1-pole C-curve miniature circuit breaker is the appropriate style instead. It is a miniature breaker rather than a molded case breaker, so it belongs in DIN rail or Multi9 equipment, not in an ABB A2 Series panelboard.
12) What is the difference between the A2A and A2N versions offered under the ABB A2 Series TMF breaker?
The ABB A2 Series TMF 3-pole breaker is sold in several models, including A2A200TW, A2A200TW-2, A2A225TW-2, A2N200TW and A2N225TW. The A2A and A2N letters designate different performance versions of the same 250 frame, while the 200 and 225 figures identify the ampere rating of the fixed thermal-magnetic trip. All of them share the TMF trip unit, 3-pole configuration and fixed-fixed mounting, so selection comes down to matching the model number on the breaker being replaced.
13) How many breakers come in an order of the ABB A2N 250 TMF?
One breaker per unit, sold each. If you are standardizing a facility or stocking spares for a plant, order the quantity you need by the piece.
