ABB TEB111020 – Frequently Asked Questions

1) What amperages and pole configurations does the ABB TEB circuit breaker come in?
The ABB E150 TEB thermal magnetic breaker is ordered by catalog number, and six are available: TEB111020 in 1-pole, and 2-pole units in 20A (TEB132020), 30A (TEB132030), 40A (TEB132040), 50A (TEB122050), and 70A (TEB132070). Pick the catalog number that matches both the pole count and the amperage on your panel schedule, since the number covers the complete breaker.
2) Can an ABB TEB breaker be back-fed as a main in a panelboard?
Yes. TEB, TED and THED breakers in the ABB E150 line are suitable for reverse feed, so a TEB can be installed back-fed where the panel design calls for it. Note that the breaker itself is what carries the reverse-feed rating; any hold-down kit your panel or the code official requires for a back-fed main is a separate item.
3) What voltage and interrupting rating does the ABB TEB 2-pole breaker carry?
The TEB is a 240V device with a 10,000 A interrupting capacity (10K IC) on the E150 frame. If your available fault current at the panel exceeds 10kA, the TEB is the wrong choice and you need a higher-AIC frame instead.
4) I need a 2-pole 50 amp breaker for a 240V circuit. Which ABB TEB part number is that?
TEB122050 is the 2-pole 50 ampere unit, rated 240V with 10kA interrupting on the E150 frame. It suits a two-conductor 240V branch circuit such as a dedicated equipment feed, and it ships one each.
5) Can I use an ABB TEB breaker on a 480V circuit?
No. The TEB units offered are rated 240V. The wider E150 line goes up to 600V AC, but that is a different catalog number within the frame, so do not apply a TEB to a 480V system.
6) Can a DIN rail miniature circuit breaker replace an ABB TEB breaker?
No. The Square D C60 UL489 miniature circuit breaker is DIN rail mount, which means it clips onto a rail inside an enclosure or control panel. The ABB E150 TEB is a panelboard and load center breaker installed into a panel interior, not onto a DIN rail. If the existing device sits on a rail in a control cabinet, a C60 style MCB is the right form factor; if it sits in a panelboard, stay with the TEB or another breaker built for that interior.
7) What is the closest thermal magnetic alternative to an ABB TEB breaker for a molded-case panel?
The Square D PowerPacT B is also a thermal magnetic molded-case circuit breaker, making it the nearest functional counterpart to the ABB E150 TEB, which uses an LI thermal magnetic trip unit. The difference is the frame and mounting interface: TEB breakers are built on ABB's E150 frame and bolt or plug into panelboards designed around that line, while PowerPacT B is a Square D frame with its own mounting and interior. They are not interchangeable in the same panelboard interior, so match the breaker to the panel brand rather than to the trip type alone.
8) What size conductor terminations will an ABB E150 TEB breaker accept, 60 C or 75 C wire?
The breaker is rated 60/75 C through 100 amperes, so you can size conductors off either the 60 C or 75 C column as your design and the terminations allow. Every TEB amperage offered, from 20A up to 70A, falls inside that 100A window.
9) What does the LI trip type on the ABB E150 mean, and is it adjustable?
LI is a thermal magnetic trip unit: the thermal element handles sustained overloads and the magnetic element handles short circuits (the L and the I). It is a fixed thermal magnetic breaker, not an electronic trip with settable pickup and delay, so the protection is set by the catalog number you order.
10) What is the difference between the ABB E150 TEB and a Square D PowerPacT B breaker?
Both are thermal magnetic molded-case breakers. The ABB TEB sits on the E150 frame, a line covering thermal magnetic breakers, magnetic breakers and molded-case switches up to 150A and 600V AC, and the TEB units offered run 20A to 70A at 240V with 10kA interrupting. The Square D PowerPacT B is Schneider's equivalent thermal magnetic molded-case family. Which one you buy usually comes down to what the panelboard is built to accept, since breakers are not interchangeable across manufacturers' panels.
11) What should I use instead of a 1-pole TEB breaker on a 120V control circuit in a DIN rail enclosure?
The Square D Multi9 C60 1-pole C-curve miniature circuit breaker is rated 120V AC and is the type of device used for that duty. The ABB TEB is offered in a 1-pole version as well, but it is a 240V rated panelboard breaker rather than a rail mounted miniature breaker, and the C-curve on the Multi9 is a defined magnetic trip characteristic for inductive control loads. Choose by the enclosure: rail mounted control cabinet points to the Multi9 C60, panelboard points to the TEB.
12) How does an I-Line breaker differ from an ABB TEB breaker?
The Square D PowerPacT Q is an I-Line circuit breaker, meaning it connects to the vertical I-Line bus stab system used in Square D I-Line panelboards and switchboards. The ABB E150 TEB connects into ABB panelboards and load centers on the E150 frame and is rated for reverse feed. Because the bus connection method differs entirely, an I-Line breaker cannot be fitted into a panel built for TEB breakers, and the reverse-feed allowance on TEB does not transfer.
13) For a facility standardizing breaker stock, which of these lines cover the widest amperage range in one series?
The ABB E150 line that the TEB belongs to covers thermal magnetic breakers, magnetic breakers, and molded-case switches up to 150 amperes and 600 volts AC, with TEB itself stocked in 20, 30, 40, 50, and 70 ampere 2-pole ratings plus a 1-pole version. Among the alternatives, the Square D PowerPacT B and PowerPacT Q are separate molded-case series, and the Multi9 C60 and C60 are miniature breaker series, so standardizing across them means carrying more than one family. Base the decision on which panel interiors are already installed across the facility.
