ABB XT3N 250 TMD 200-2000 3p F F 50C 1SDA070162R1
Description
XT3N 250 TMD 200-2000: a 200 A breaker from the 250 A Tmax XT3 frame
XT3N 250 TMD 200-2000 3p F F 50C (order code 1SDA070162R1) is a fixed three-pole breaker from the Tmax XT3 frame, which is sized for 250 A. This unit is the 200 A step, with the performance level N (36 kA at 415 V AC) and a thermomagnetic TMD trip unit calibrated at 50 C.
At this rating the breaker is usually applied as the incomer or feeder protection of a sub-distribution board. The XT3 uses TMD trip units with a fixed instantaneous threshold.
Technical specifications
| Parameter | Specification |
|---|---|
| Order code | 1SDA070162R1 |
| Type designation | XT3N 250 TMD 200-2000 3p F F 50C |
| Frame / breaking class | Tmax XT3, size 250 A, performance level N: Icu 36 kA at 415 V AC |
| Rated current In | 200 A (I1 adjustable 140 to 200 A) |
| Short-circuit trip I3 | 2000 A, fixed at 10 x In (TMD) |
| Poles | 3 poles under this code; 4-pole version 1SDA070169R1 (neutral 100 %) |
| XT3 TMD range in the catalogue | In 63 to 250 A; 50 % neutral available for In 125 A and above (125 A neutral at the 200 A rating) |
| Standard / protection | IEC 60947-2; moulded-case circuit-breaker, fixed version with front terminals (F F) |
| Calibration | Thermomagnetic trip unit calibrated at 50 C (this is the 50 C code, not the standard 40 C code) |
| Overload protection (L) | Adjustable I1 = 0.7 to 1 x In, inverse long-time curve |
Trip behaviour and neutral options
The overload threshold is adjustable from 0.7 to 1 x In, which gives 140 to 200 A for this breaker. The instantaneous threshold is fixed at 10 x In, that is 2000 A. Because the magnetic trip is not adjustable, the downstream cables and the upstream selectivity have to be checked with this fixed value in mind.
For the four-pole breaker (1SDA070169R1), the neutral can be 100 percent. The catalogue also lists a 50 percent neutral for In of 125 A and above; for the 200 A rating the 50 percent neutral values are 125 A thermal and 1250 A magnetic.
Disconnector and range context
The XT3 range runs from 63 A to 250 A. The matching XT3D 250 switch-disconnector (1SDA068210R1, three poles) is rated Icw 3 kA and complies with the AC21A, AC22A and AC23A utilisation categories, with 200 A in AC23.
For the performance level S (50 kA at 415 V), the catalogue lists the XT3S 250 TMD 200-2000 under 1SDA070176R1, which is a different order code; choose according to the available fault level.

About brand
ABB is the Swiss-Swedish engineering group for electrification and automation: low voltage drives, motors, circuit breakers and motor control, process instruments and analysers, control systems and robots. It was formed on 5 January 1988 by the merger of two older companies. ASEA was founded in Västerås, Sweden, in 1883 by Ludvig Fredholm to make electric lighting and generators. BBC Brown Boveri was founded in Baden near Zurich in 1891 by Charles E. L. Brown and Walter Boveri. ABB Ltd is incorporated in Switzerland, headquartered in Zurich and listed on the SIX Swiss Exchange and Nasdaq Stockholm.

Choosing an ABB drive
ABB's ACS drive codes are easy to read once you know the pattern. In ACS580-01-046A-4, "ACS580" is the drive family, "01" means a wall-mounted single drive, "046A" is the rated output current (about 46 A) and "-4" means a 380–480 V supply. The family is chosen by application: ACS355 for compact machinery, ACS310 for simple pumps and fans, ACS580 as the general-purpose drive, ACQ580 for water and wastewater with pump functions such as pipe fill and dry-run protection, and ACS880 for heavy industrial duty with direct torque control. Size the drive on the motor's full-load current, not only its kW rating, and allow derating for the high ambient temperatures common in Gulf electrical rooms.
Where ABB products are used
In Oman and the GCC, ABB drives and motors run pumps, fans and compressors in water and wastewater plants, district cooling, oil and gas and industry. ABB flowmeters, level instruments and analysers are used in water utilities, power and desalination plants and refineries, and SACE breakers protect switchboards in buildings and plants.
