ABB XT1N 160 TMD 100-1000 3p F F 50C 1SDA070106R1
Description
XT1N 160 TMD 100-1000: a 100 A Tmax XT1 breaker calibrated at 50 C
XT1N 160 TMD 100-1000 3p F F 50C, order code 1SDA070106R1, is a fixed three-pole moulded-case circuit-breaker from ABB’s SACE Tmax XT range. The XT1 frame is 160 A, performance level N gives 36 kA at 415 V AC, and the thermomagnetic trip unit has a rated current of 100 A.
What makes this code different from the common XT1 order codes is the 50 C calibration. ABB’s 50 C catalogue states that the thermomagnetic trip units are calibrated at a reference temperature of 50 C, which is relevant where the breaker sits in a hot enclosure.
Technical specifications
| Parameter | Specification |
|---|---|
| Order code | 1SDA070106R1 |
| Type designation | XT1N 160 TMD 100-1000 3p F F 50C |
| Frame / breaking class | Tmax XT1, size 160 A, performance level N: Icu 36 kA at 415 V AC |
| Rated current In | 100 A (I1 adjustable 70 to 100 A) |
| Short-circuit trip I3 | 1000 A, fixed at 10 x In (TMD) |
| Poles | 3 poles under this code; 4-pole version 1SDA070114R1 (neutral 100 %) |
| XT1 TMD range in the catalogue | In 25 to 150 A; 50 % neutral only for In 125 A and above |
| 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 unit and settings
The TMD trip unit protects against overload with an adjustable threshold of 0.7 to 1 times In, so for this 100 A unit the thermal setting runs from 70 to 100 A. Short-circuit protection is instantaneous at a fixed 10 x In, which is 1000 A for this breaker.
Four-pole versions of the same breaker have 100 percent neutral protection under the code 1SDA070114R1. The catalogue notes that a 50 percent neutral is only available for In of 125 A or more, so a 100 A unit does not offer it.
Where it fits in the XT family
In the ABB table the XT1 range runs from 25 A to 150 A for the performance level N (36 kA), while the XT1C version is 25 kA. The XT1 sits below the XT2 (160 A with adjustable magnetic setting) and the XT3 (250 A) in the range.
The catalogue also lists the XT1D 160 switch-disconnector (1SDA068208R1, three poles) with Icw of 2 kA for isolation duty. A disconnector has no automatic trip, so it has to be protected by a coordinated device upstream.
Documents and quotation
The linked file is the ABB SACE Tmax XT 50 C technical catalogue – ordering codes 1SDC210064D0201. Seven Star LLC supplies the 1SDA070106R1 on request from Muscat as an independent supplier; availability and lead time are given in the quotation. More products of this kind are in the Circuit Breakers category, and a related item is the ABB SACE Tmax XT moulded case circuit breaker family page.
Confirm before ordering: the calibration temperature (this code is the 50 C version), number of poles and neutral rating, the prospective short-circuit current at the installation, the trip setting needed and any accessories such as shunt or undervoltage releases.

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.
